## About The Pull Request
1. Deletes `special_step_sounds`. Unused anyways.
2. Human footstep type is now determined by its legs.
- This means a human with two different legs, with two different
footstep types, now alternate between footstep type every other step.
3. Digitigrade legs now use claw footstep sfx
## Why It's Good For The Game
Less random species vars, more dynamic human code, and a little bit more
immersion
## Changelog
