Allow regular expressions in prefixes

[elboletaire]

I come from overviewer where we could define these via regular expressions, and that really reduced my config a lot, since now I have to add multiple definitions to check stuff like uppercase (i.e. I have three prefixes for "portal": Portal, portal & PORTAL)

A way to define to ignore case would also be welcome, but having case sensitive regular expressions would already simplify it a lot.

I came from overviewer also and it was a lot simpler to have a script that watched for these signs.

This is a good idea. Thank you for sharing!

@elboletaire, I have merged the PR (#72) for this update to main. Take a look at https://github.com/tpwalke2/BlueMapSignMarkers?tab=readme-ov-file#example for an example of how to configure the regex marker group.

There are a few other items I am targeting for the same version (1.21-0.4.0), however. You can track the progress of those issues here: https://github.com/tpwalke2/BlueMapSignMarkers/issues?q=is%3Aissue+is%3Aopen+label%3A1.21-0.4.0
