CLEANUP: cleans up dependencies to use workspace version

CLEANUP: standardizes on pretty_env_logger
NEWBIN: Adds gemmarat to use Ratatui as an interface
CLEANUP: removes debugging display from computer.rs
ENHANCEMENT: Constants for locations of test roms built from environment
BUGFIX: SoundTimer was using i32 internally when it needs to be u8
CLEANUP: removes commented code used during diagnostics
