hot reload function

[Eddio0141]

For the sake of faster development

• This will be done via patching all UniTAS methods at runtime to the one from disk
• It will be provided to the lua interpreter as reload function
  • reload("~/src/UniTAS") giving it the project path will grab the release build automatically
  • reload("~/custom/dir/something.dll") giving it a direct path to the dll also works
• Methods will be patched via harmony
  • If a method accesses a field that doesn't exist, it'll create a fake field in either a new class's instance loaded elsewhere (probably a separate AppDomain) for field access, or a dictionary to grab that field from, and replaces any access to that field through ilcode manip
  • If a new method is detected, create a dynamic method, where all ilcode access is replaced with that
  • If a new type is detected, similar to the case where field doesn't exist, along with new methods for it
• This MUST be done in a repeatable way, all of this should "just work" unless a preloader patcher change or something very specific changes
• Should also redo all harmony patches just in case!
