Add PylonRecipeProcessor

[LordIdra]

Adds a new abstraction for machines which process recipes. This is the first of 2 abstractions that will be used to create GUI machines which process recipes much like AContainer (the second abstraction will be concerned with inventory management).

Also adds a new postInitialise method which is invoked after either constructor is invoked. This was starting to be necessary for a few different use cases.

Usage:

1. call setRecipeType in your create constructor
2. call setProgressItem in your postInitialise method (if using a progress item)
3. use startRecipe to start a new recipe
4. the current recipe will be ticked automatically, and when it finished, onRecipeFinished will be called (which must be implemented)
5. override tick and add your recipe start logic, and any other ticking logic like particles, making sure to call PylonRecipeProcessor.super.tick
6. that's it
