To Reproduce

Start lute on python 3.12 on version 0.3.4.0

Extra software info, if not already included in the Description:

Python version 3.12.1

One implicit aspect of this bug is that there actually needs to be an increase in the scope of testing to encompass 3.12. Right now testing is done for 3.8 to 3.11.

I can run Lute 3.4.0 with Python version 3.11, but I can't run it with Python version 3.12 too

This fixed worked for me in 3.12. Going to open a PR.

def init_parser_plugins():
    """
    Initialize parsers from plugins
    """
    if sys.version_info.major == 3 and sys.version_info.minor in (8, 9, 10, 11):
        custom_parser_eps = entry_points().get('lute.plugin.parse')
    elif sys.version_info.major == 3 and sys.version_info.minor == 12:
        custom_parser_eps = entry_points().select(group='lute.plugin.parse')
    else:
        custom_parser_eps = []
    for custom_parser_ep in custom_parser_eps:
        if _is_valid(custom_parser_ep.load()):
            __LUTE_PARSERS__[custom_parser_ep.name] = custom_parser_ep.load()
        else:
            raise ValueError(f"{custom_parser_ep.name} is not a a subclass of AbstractParser")

Should be solved by

• fix init_parser_plugins for python 3.12 #425

Thanks very much @cghyzel -- merged into develop, and github ci was extended to include python 3.12.
