[feature] - v option to print mptsd version (for automated bash script)

[SonnyWalkman]

Hello @gfto and @lars18th,

Is it advantageous we add an option -v to print mptsd version? I added it to config.c however my addition in my build simply prints version 1.0.0.1. Currently when mptsd starts it prints some longish system info and build date?

I'd suggest a version.h and update it every build.

Version 1.1.0.1234 ?

release.major.minor.build

It'll be able to be managed moving forward to "track" later versions?

I added it to my build for the purpose of making my install script check mptsd is on the system looks at the version and if there is a later release? asks to upgrade to the later release.

Great work, I have it running on Ubuntu 23.10 no issues so far until I see what it can do..
