padmgr and related (#71)
* In process of moving changes over from old repo

* Merged in changes

* Finished import of padmgr changes from old repo

* Adjusted some volatile

* Improving padmgr volatile situation

* Almost matched osReadMempak

* Working on osMempakDataCRC

* Explanations and equivalents but no matches for osMempakAddrCRC and osMempakDataCRC

* OK after merge

* Matched osMempakAddrCRC and osMempakDataCRC

* Matched osReadMempak

* Updated PadMgr function names to be less like original code

* Changed variable names to make them further from original code

* Changed names and it stopped matching

* Undid clang-format steamrollering whitespace memes

* Cleaned up Input names

* More formatting changes

* Moved padmgr to z64.h, deleted padmgr.h
