resolves #179

I haven't tested this in any comprehensive way, only with my primary keymap. I'll drop a link into the rmk issues and maybe others can test there

Thank you for the contribution! I am very unfamiliar with RMK so apologies if I am asking things that I can learn by looking them up. Overall the code looks simple enough, but please see review comments.

If you don't get around to them I will eventually take a look myself but given the amount of asks there were for RMK so far, it might be a while.

Pull Request Overview

This PR adds support for parsing RMK (Rust-based keyboard firmware) TOML keymap files. RMK uses a TOML-based configuration format, which differs from the devicetree format used by ZMK and JSON format used by QMK.

Key changes:

• New RmkKeymapParser class that handles TOML parsing, layer extraction, combo parsing, and physical layout detection
• Configuration option rmk_combos for customizing combo visualization
• CLI integration with -r/--rmk-keymap flag

Reviewed Changes

Thanks for taking time for the detailed review. I will work through the remaining suggestions tomorrow afternoon when I can test as I go through them...

I think all the review comments have been addressed now. I have tested it on a couple of different keymaps and it seems to be running well.
