Villagers sell spawn eggs

This mod adds 4 new villager jobs that each sell spawn eggs.
Almost every spawn egg in game is now buyable.
The reason there are 4 villagers is to make sure you can buy all the spawn eggs without needing to hope the right one unlocks at the next level.

The villagers all have a coloured hat do distinguish between them.
Want to make nicer textures for them? let me know on discord

Ideas for the future:
Requiring a mob drop to buy the egg to make it a bit harder
Different version for different price levels

let me know if someone is interested in these ideas and I'll work on it
