Peg reads Modtap keycodes as two separate keys

[ptaranat]

When using Modtap module, Peg tries to read KC.MT(KC.ESC, KC.LCTL) as two separate keys KC.MT(KC.ESC and KC.LCTL), likely because of splitting based on , identifier.
This results in two keys showing up as error, and shifting the entire layout by one key.
A fix would be to check if there is a function denoted by parens, and to ignore all commas within that parens

Note how entire layout shifted one key to the right.

Workaround:

1. In the GUI, add the Custom Keycode where the Err is.
2. Edit the layout in main.py and remove the KC.NO next to it.
3. Restart Peg.
