[MIRROR] Fishing expansion 2: one-year later boogaloo

About The Pull Request

This PR mainly adds more fish and more fishing spots to the game, while refactoring a few aspects of the fishing minigame.

Listing out with the new fish:

Arctic char: mainly filler content for the ice hole fishing spot
Sockeye Salmon: ditto but also provides better fillets that boost the quality of resulting food items when cooked or used in recipes
Soulfish: joke content, found by the cursed spring ruin
Skin Crab: also a joke found by the cursed spring
Bump-Fish: filler for the sand fishing spot
Burrower Crab: ditto, reusing a fish sprite I made last year
Sand Surfer: ditto
Three-Eyed Goldfish: It's a reference, doh
Stingray: A modestly weaponizable fish (whoops I've forgot to set the hit sounds), it possess a few traits that make it deliver bits of venom each time you hit someone with it
Swordfish: Huge-ass fish that may require two hands to wield (or not, if the RNG wants to make it smaller). Stats-wise, it's more or less the equivalent of the captain sabre, if not stronger (and more unwieldy due to size and weight). Becomes weaker when dead. Also gives better quality fillets.
Chainsawfish: A mutation of the goldfish with some size, weight and traits requirements, but can also be found on emagged fishing portals. Stronger than the swordfish, it behaves sort of like a chainsaw, with the similar tool behaviour and var values. Also becomes weaker when dead.

As for the fishing spots, you can now fish on sand turfs, at the cursed springs or on ice. Rivers/jungle water now has its own fishing spot datum, and no longer uses the generic fishing portal one. To fish on ice, you first have to carve a hole with a pick or a shovel.

I've also refactored the fish "AI" hardcoded stuff used in the fishing minigame into their own datums, which let me add a few fancier ways to how the fish moves during the minigame (i.e. the soulfish moving at 1 FPS or the chainsawfish getting faster and faster).

As for the sword and chainsaw fish, their potential strength is balanced out by the need of keeping them alive, as well as the potential cumbersomeness, two-handed wielding and potential slowdown from the excessive weight of the fish (Thank you Big Slappy for the inspiration).

Other minor changes include: Pufferfish giving better quality fillets (too bad they're poisonous, I'll go and make a skillchip to let cooks safely separate the poisonous liver from the fillets); McGill The lawyer's goldfish) having a 15% of being three-eyed; the aforementioned slowdown from fish weight and two-handed carry from fish size; a couple new fish icons (the ones that hint you on what you're trying to catch) for the fishing minigame; a few adjustments to prevent self-reproducing fish from ignoring the population cap and let fish with a stable population of 1 to crossbreed (also gotta make a different PR to let it happen rarely without the crossbreeding trait).

This PR is still a WIP, gotta test it several times.

Why It's Good For The Game

Fishing is something I've been working on for about a year now, but there are still a few places where it's kinda lackluster, like there's not enough diverse fishing spots or useful fish (I'll be working on a separate PR to make the logistic of a carrying a fish around without letting it die a tad easier). Also, look at these sprites:

new fish

Can you guess which is which?

Changelog

For the sake of not dumping players with niche information 90% of the players won't understand, I'll keep the CL pretty generic

:cl: add: Added twelve new fish types to the game. Some are cool, other are not, some come with their own special traits and some are straight-up weapons. add: Added more fishing spots to the game. Sand, ice, rivers, the cursed spring... balance: A few fish like salmon, swordfish and pufferfish (poisonous btw) now give better quality fillets when butchered, which can improve the quality of food that uses them even further. balance: Excessive fish weight will make the fish slowier to carry, while excessive size may make it require two hands. balance: Adjusted size, weight and cooldowns of several fish, for the better. /:cl:
