sm64core

This is a an attempt to create a fairly accurate recreation of the Super Mario 64 character controller in Godot.  

SM64 character controller is an absolute beast spanning 300+ states. We have cut it down to just the core movement, jumping(there are like 5 different jumps), sliding, wall jumps, ledge grab. Still some of it is missing and its imperfect but the game-feel is approaching a decent approximation.

I pointed MuseSpark 1.3 at the https://github.com/libsm64/libsm64  to analyze and spec out the state machines and state flows as well as a bunch of the numeric values.  Made a bunch of gate tests based on the real movement and recorded velocities.
