Add raw port option for server mainloop sub-command

[CyrosX]

I just wanted to share my little setup shell script creation. This needs lprint to be installed already. I did this via apt & the Debian repositories on dietpi (7.7) - Raspberry Pi Zero W.

The script creates a 9100 + 9102 (JetDirect) stream accepting systemd socket & service for receiving raw printing data and a lprint-server service (%H is the hostname) This allows the additional usage of Dymo Connect on Windows. You need to create the printer connection and use the original drivers, else the printer/s won't appear in the label software. This wasn't working when I've tried to use IPP on Windows - on MacOS IPP works fine. I've only found xinet.d / inetd solutions on the internet.

Happy to hear suggestions for improvement :-).

@CyrosX Thank you for this contribution, however there are a couple small things to note:

1. PAPPL already supports a "native" option for managing port 910x printing, so the next version of LPrint (which is based on PAPPL) can just provide access to that option instead.
2. Windows 10 and higher supports direct printing via IPP, so once the new version of LPrint is out you won't need to use the hack of port 9100 and the Dymo driver. Instead you can just discover the printer and print directly!

I'm moving this bug over to the PAPPL project so that I can add a standard option for controlling server options like this.

The new option will be:

lprint server -o server-options=raw-port
