Refactor Phase 1

After reading 99 BOOP, which by the way is an excellent read, I refactored the code base.

I also used rubocop to improve styling, reek to identify code smells, and flog to evaluate ABC metrics.

There is still a substantial amount of work to be done, but the code quality has improved substantially.

Minor Patch

Fixed an issue where a conditional was left out causing a bug during game-play.

Implementation of Chess

Fully implemented Chess according to standard specifications.
Have not met the Odin Project's final specification of save files and loading.
