How to add code highligthing for a new langage?

[Trophime]

Hi, I wonder how to add support for a new langage.

I would like to give try to presenterm for creating slides for students. The idea is to present the use of gmsh.

I would like to have basic support for the geo file format of gmsh just like the gmsh-vscode extension .

Thanks for your feedback. Best

This uses bat under the hood to actually do all the syntax highlighting. If the language is supported by bat then it should be as easy as https://github.com/mfontanini/presenterm/pull/361, otherwise this is in the same boat as https://github.com/mfontanini/presenterm/issues/271

Closing, feel free to reopen if needed. See #388 also for a way to invoke bat directly.
