LDtk support

[jeremyfa]

The LDtk editor from @deepnight (https://ldtk.io/) is getting better and better.

It would be great if it was compatible with Ceramic as it would bring a full featured level editor around.

This can be done in multiple steps:

Step 1

• [x] Read .ldtk and .ldtkl files so that they are usable as Ceramic tilemaps.

Expose LDtk specific data as well (just like what was done with TMX raw data being exposed when loading Tiled data)

Step 2

• [ ] As Ceramic already has an auto-tiling system that supports blob and wang sets, extend its capabilities to support a rule system similar to LDtk’s.

• [ ] Parse LDtk rules into usable rules in Ceramic runtime directly

This opens the door to editing maps that can re-apply rules in game while still being compatible with LDtk editor as well

Step 3

• [x] Explore how the entities system of LDtk could be better integrated with Ceramic

Feedback is appreciated if you have any, before I start implementing it.

Will probably start working on that in the coming weeks 😊

First step is starting to work.

Now actually working on Step 3: add an easy way to instanciate entities with a built-in implementation provided by Ceramic
