[ANN] Alternative Firmata protocol explanation

[martin-eden]

Recently I've finished documentation of standard Firmata protocol (for myself mostly).

Take a look at https://github.com/martin-eden/firmata_protocol/blob/main/protocol.md

One style, railroad diagrams and no excerpts from C code.

(This is just announce for maintainer, not an issue. Maybe it can be added to some list (as with list of implementations). You can resolve it.)

This is really nice! Love the railroad diagrams. Much easier to read IMO. Will have to look into how to create those railroad diagrams.
