* implement/match CalcLocalTransform
* fix odd build error
* address feedback
move vec.h to thirdparty folder
update vec.h
move all realtime code to realtime folder
move calclocaltransform out of legoutil and into realtime
cast shift to MxS32
add additional unroll hack to CalcLocalTransform to prevent msvc entropy
* All of the MxVectors share an inheritance chain. MxVector4 inherits
from MxVector3 which inherits from MxVector2.
* They all operate on a shared `float*` data member which points to the
underlying storage.
* There are also MxVector3/4Data classes, which inherit from Vector3/4,
but add concrete storage for the Vector data rather than just an
abstract data pointer.
* The same is true for MxMatrix, with there being an abstract and a
concrete variant of it.
* Also improve reccmp.py register matching algorithm. It previously
could not recognize an effective match when a swap had to take place
between two registers used on the same line. It turns out this happens
a lot in floating point math code so I adjusted the implementation to
break the disassembly lines on spaces rather than just linebreaks
allowing the existing effective match code to handle that case too.
