Proc Type API (#513)

* ive got a bad feeling about this

* worst mistakes

* network settings and IL fix

* hashing and clean up

* memorize tests and optimization

* basic documentation and get modded mask overload

* add stripped patch

* update hash function

* basic readme

* doktor, turn off my memory inhibitors

switch underlying data from bool[] to byte[], add GetRaw versions of public mask access

* some internal documentation

* documentation and ts updates

* fix patcher encapsulation

* Improvements to ProcTypeAPI
