feat: feature work

[bconlon1]

General

• All ore rates have been tweaked.
• All aercloud rates have been tweaked and distributed according to different world height layers. The shape of aerclouds has also been tweaked as well.
• The Aercloud Sea can now have patches of Green or Blue Aerclouds in it.
• The top branches of all Greatroot tree variants have been adjusted.
• Caves above the Aercloud Sea boundary now have chances to spawn coarse dirt patches on floors and ceilings, with the commonality increasing as the y-level increases. Ceiling patches have the chance to spawn hanging roots, and floor patches have the chance to spawn holystone rocks.
• Surface caves can also generate patches of coarse dirt and aether grass (or enchanted aether grass in irradiated biomes), which generates short grass on top of it.
• Patches of coarse dirt and roots can also spawn under open overhangs when not in caves less commonly.
• Add Shimmering Silt to lakes.
• Add a first iteration of Bryalinn moss; doesn't generate yet, needs visual design work.

Highfields

• All Highfields biomes can generate Skyroots, Skyplanes, Wisproots, and Greatoaks.
• Skyroot's height variation has been adjusted to allow it to generate slightly taller for forests, but the normal short variant still exists for fields.
• Skyplanes have been reworked to be more accurate to concept art; the tops are flatter and more stepped allowing for easier navigation on top of the Shrouded Forest. They also no longer have leaf decay issues.
• Wisproots have been given variation to let them have a flatter top, similar to concept art.
• Greatoaks have had their height variation adjusted, and have a short variant for fields and a tall variant for forests.

Flourishing Field

• Short Grass now has field-like placement and alternates between different length variants.
• Valkyrie Sprouts spawn with streak-like placement.
• Highlands and Blueberry Bushes spawn in condensed and clumped patches.
• Flower placement has been adjusted slightly to be less common.
• Holystone Rocks will spawn randomly.

Verdant Woods

• Tree density has been adjusted to be somewhat less dense.
• Quicksoil generates slightly less commonly.
• Grass spawns in patches of three different types: Small (only Short Grass), Medium (Short and Medium Grass), and Large (Short, Medium, and Long Grass).
• Valkyrie Sprouts spawn with streak-like placement.
• Highlands and Blueberry Bushes spawn in condensed and clumped patches.
• Holystone Rocks will spawn randomly.
• Skyroot Twigs will spawn randomly.
• Orange Trees spawn occasionally in this biome.

Shrouded Forest

• Tree density has been adjusted to be much more dense to block out sunlight.
• Trees will naturally have the chance to generate with permanent leaf pile patches beneath them.
• Quicksoil generates slightly less commonly.
• Grass spawns in patches of three different types: Small (only Short Grass), Medium (Short and Medium Grass), and Large (Short, Medium, and Long Grass).
• Highlands and Blueberry Bushes spawn in condensed and clumped patches.
• Holystone Rocks will spawn randomly.
• Skyroot Twigs will spawn randomly.
• Mossy Holystone boulders will spawn randomly alongside clusters of Holystone Rocks.

Shimmering Basin

• Short Grass now has field-like placement and alternates between different length variants.
• Valkyrie Sprouts spawn with streak-like placement.
• Highlands and Blueberry Bushes spawn in condensed and clumped patches.
• Holystone Rocks will spawn randomly.
• Orange Trees spawn occasionally in this biome.
• Fallen Skyroot Logs will spawn in this biome as driftwood; they can spawn on the shore and in shallow water.

Magnetic

• All Magnetic biomes can generate Skybirch, Wisptops, and Greatroots.
• Skybirch has been reworked to be closer to concept art and have less leaf decay issues.
• Blueberry Bushes spawn in condensed and clumped patches.

Magnetic Scar

• Short Grass now has field-like placement and alternates between different length variants.
• Holystone Rocks will spawn randomly.

Turquoise Forest

• Grass spawns in patches of three different types: Small (only Short Grass), Medium (Short and Medium Grass), and Large (Short, Medium, and Long Grass).
• Holystone Rocks will spawn randomly.
• Skyroot Twigs will spawn randomly.

Violet Highwoods

• Grass spawns in patches of three different types: Small (only Short Grass), Medium (Short and Medium Grass), and Large (Short, Medium, and Long Grass).
• Holystone Rocks will spawn randomly.
• Skyroot Twigs will spawn randomly.
• Fallen Wisproot Logs will spawn in this biome.
• Trees will naturally have the chance to generate with permanent leaf pile patches beneath them.

Arctic

• All Arctic biomes can generate Skypines and Greatboas.
• Skypines have been tweaked to be more accurate to concept art and have less leaf decay issues.
• Skypines and Greatboas have decorators for automatically placing snow on top of them, spawning twigs beneath them, and replacing any snow blocks beneath them with grass blocks.
• Roots in this biome are frosted and drip snow particles.
• Overhangs can spawn with Ice Crystals beneath them with packed ice patches instead of roots.
• Coasts have been given a more spikey underside with hanging packed ice blocks and ice crystals.

Frigid Sierra

• Short Grass now has field-like placement and alternates between different length variants.
• Icestone Boulders will spawn randomly.

Enduring Woodland

• Grass spawns in patches of three different types: Small (only Short Grass), Medium (Short and Medium Grass), and Large (Short, Medium, and Long Grass).

Frozen Lakes

• Short Grass now has field-like placement and alternates between different length variants.

Sheer Tundra

• It will now rain in this biome up to a certain y-level.
• Short Grass now has field-like placement and alternates between different length variants.
• Icestone Boulders will spawn randomly.
• Mossy Holystone boulders will spawn randomly alongside clusters of Holystone Rocks.
• Noise and height based snow placement is used for this biome to add surface variation of snowy and non-snowy areas.

Irradiated

• Trees now use a decorator to generate with a tan->white leaf color gradient.
• Grass spawns in both patches and field generation.
