Prehistoric Spawns 2.1 (1.12.2)

[2.0] Completely overhauled the mod! Configuration now uses a JSON format that allows for spawn packets to be added or removed at will, meaning it is possible to add spawns for any registered biome, modded or vanilla. BOP spawns are generated by default if BOP is installed when Prehistoric Spawns is loaded for the first time.
[2.0] Overhaul now uses F&A 8.0.6 and LLibrary 1.7.20.
[2.1] Fixed a typo in autogenerated configs preventing megaloceros from spawning. To fix this in existing games, please either delete prehistoric-spawns.json from your config folder, or edit the config and change "megalocerus" to "megaloceros".
