Custom Machinery 1.21-0.10.5

Additions :

• Very big refactor of the recipe processing system, the syntax didn't change so existing recipes don't have to be changed.
• However, it is possible that some bugs happen like requirements not being processed correctly, if that happen please report it.
• A machine can now run multiple recipes in parallel, this only work with the 'machine' processor (which is the default).
  • The machine processor now has an "amount" properties which define the amount of cores the processor can use.
  • Each core can process exactly 1 recipe at a time, so the amount of core define the max amount of recipes that can be processed at a time.
  • If the "amount" property of the machine processor is set to 1 (default) the machine exactly like it did in previous versions.
  • Machine recipes can be set to run on every core, only on specific cores, or on any core but once at a time.

BugFix :

• Fix jei not differentiating machine items.
