localtileserver fails with flask==3

[dfguerrerom]

Flask 3.0 was released last week, and now localtileserver will use this version during the requirements installation
I think flask<3 has to be pinned until the code is refactored.

Full traceback:

Thanks for pointing this out! Looks like an issue with flask_restx. I'll pin the dependencies for now and issue a patch release

Looks like this was fixed upstream via python-restx/flask-restx#567, so I'm going to merge #191 to free this
