Multiple runs on Linux crash due to issues with loading config

[caldwellb]

when running zxlive on linux, the first run will properly grab the system font size setting. on exiting the program, it saves to a file ~/.config/zxlive/zxlive.conf, and on subsequent runs the error message below appears.

  File "/usr/local/bin/zxlive", line 5, in <module>
    from zxlive.app import main
  File "/usr/local/lib/python3.12/site-packages/zxlive/__init__.py", line 17, in <module>

    raise ValueError(f"Unexpected type for {val}: expected {_type}, got {type(val)}")
ValueError: Unexpected type for 11: expected <class 'int'>, got <class 'str'>

The ValueError for 11 refers to the font size loaded from ~/.config/zxlive/zxlive.conf. Deleting the folder ~/.config/zxlive will fix this issue temporarily.
