Add text message port cli option

[digitaldisarray]

What did you change?

I added a command line option '--textport' that lets you send text to an arbitrary port number.

Why did you change it?

When developing a new meshtastic firmware module, there isn't a super easy way to send arbitrary text packets to a module. Previously, module developers that just want to receive text data for testing purposes would likely make their module receive normal text messages (port 1) during development which is a bit of a hack-y solution. Or, developers would have to leave the comfort of their command line and write a script to send the messages on the custom port.

IMO this should be limited PRIVATE_APP. We don't need to easily allow folks to send arbitrary payloads over common portnums like position and telemetry for instance

[digitaldisarray]

That makes sense. I'll modify my PR when I have the time to just be for PRIVATE_APP.

Agreed on the proposed change. I've set off the CI build in case it brings up anything else that could use improvement, for whenever you get back to it.

[digitaldisarray]

Thank you for your patience. I believe the changes I just made limits users to PRIVATE_APP in a reasonable way. Let me know if any other changes should be made. I'll get to them quicker this time :)

This looks good to me, sorry for the delay in re-checking it. Assuming that CI doesn't complain about anything, I'll get this merged soon.

Ah, spoke too soon. I guess it's got some issues with syntax, possibly needs some quote-shuffling. I'll try to take a look when I get chance if you don't first.
