I don't know if it is actually safe to delete these here. I needed to remove them to run the test code on my host machine. Removing them didn't seem to break anything but that might not be the case on the real keyboard and needs to be tested/confirmed

Summary
Replaces the parser with a token based parser. This allows for easier changes and additions to the language. It allow allows for easy fixes for the "comma in string" bug. This change also fixes small typos found in other parts of the firmware
Features
For the most part this should be a drop in replacement for the previous parser. The only known changes are listed below
[COMMA]=>,substitution has been removed as it is redundant now[RETURN]and[SINGLE QUOTE]have been added as substitutionsR0, K0: 0x01+0x02+0xFFTesting
This feature was not tested on real hardware (I haven't build the keeb yet :) ) but the code maintains the previous implementations public interface (via
parse_layer_definition()) and the language itself is thoroughly tested to ensure correctnessThe test can be ran with
python3 Firmware/parser_test.pyortime python3 Firmware/parser_test.pyfor timing stats
