Map Chunk Parsing

[nickelpro]

~~Milestone on deck per feature roadmap~~

This feature is mostly complete, with only housekeeping left to be done

• [x] Working parser (Still needs MultiBlockChange)
• [x] C Interface core for accessing block data :running:
• [x] Python plugin for loading and dependency resolution

[nickelpro]

Need to build a generator for the global block palette. The information is now correctly stored inside SMPMap but there's no interface to get at it, and even if you could it would be meaningless without a palette to get useful data out of.

Interface is minimally complete. Need to make the global palette available to continue moving forward on physics
