Configurable keys 2 (Mapping keys to commands) (#268)
* Add convenience/clarity wrapper for Range initialization * Add keycode parse and display methods * Add remapping functions and tests * Implement key remapping * Add remapping book entry * Use raw string literal for toml * Add command constants * Make command functions private * Map directly to commands * Match key parsing/displaying to Kakoune * Formatting pass * Update documentation * Formatting * Fix example in the book * Refactor into single config file * Formatting * Refactor configuration and add keymap newtype wrappers * Address first batch of PR comments * Replace FromStr with custom deserialize
