Make the Krake parse and accept the GPAP protocol (with alarm number and alarm id)

[RobertLRead]

Dear @TheBakedPotato,

As discussed in an issue at the GPAP repo, @nk25719 and I have decided not to use your suggestion of moving to a CSV-style protocol.

This issue is for you to code the Krake to accept that protocol. I assured her that you could easily code this protocol (which is admittedly an estimate rather than certain knowledge) and that I would help you if not. So I would like you to begin coding the Krake C++ code to accept this protocol, and in particular to parse out the 3-digit alarm number in square brackets and the hexadecimal number in curly brackets. This needs to be done for two reasons: we need the number to find the correct sound file to play, and we need to present the content text without those parts (because the operator should not see them on the krake screen.)

I suspect this will be child's play for you---but here are two approaches.

1. You could use a C++ regex library. I would probably do that because it creates maximum extensibility for the future.
2. It is very easy to code this by hand, since you "lexically" just look for the open square bracket/curly brace and then just read characters until you find the close.

Modular Protocol Friendly

I would like to add a requirement.
The code should be structured such that the parsing of the protocol is modular so that for other applications a different parsing could support other protocols.

Another Protocol

There is a protocol I would like Krake to support. the so called SCPI,

Please refer to an exact version number of the GPAP.

Regarding, "...(with alarm number and alarm id)"
Please refer to an exact version number of the GPAP.
Change to the protocol will be disruptive to all Krake Volunteers and ADaM users and testers and must happen in structured sprints so that not only the Krake (with GPAD_API) is migrated but also our PMDs and other testing tools.

Release Notes

Where applicable, the change should be documented in a FROM: , TO:, ADD: fashion.

Regression

Exact test strings developed at the release of a new GPAP version.

With respect to using a regex library, I cannot find a way to do that effectively for the ESP. The header file regex.h is accessible but there is no .cpp file to combine it with to make the translation unit. Including regex.h in a source file will result in a compilation error.

There is tiny-regex which does not use dynamic memory allocation. This would be perfect for an MCU but it lacks the crucial regex feature necessary to properly parse a protocol: capture groups.

[RobertLRead]

Okay --- can you code the sub-parts by hand? Since they are one level deep, and have constrained form with no escapes, I assume this is easy.

Oh, yeah. That I can do. Been working on it this week. lol. Since the regex approach was suggested I figured it deserved addressing in a comment if I wasn't going to go that way. :)
