[BUG] - Logger throws error if sys.modules.items changes size

[Apfelkuchen]

Describe the bug
When using L1Q 2.23.0 for wmiqc, we get a RuntimeError: dictionary changed size during iteration. line 44, in _showwarning in laboneq/controller/laboneq_logging.py.

We can hotfix this at the moment by casting the returned object to tuple or list, i.e. we change (line 44 in laboneq_logging.py)

for modname, module in sys.modules.items():

to

for modname, module in tuple(sys.modules.items()):

Versions used:

• laboneq: 2.23.0
• zhinst-core: 23.10.52579
• wmiqc: 0.57.4

Context

• Do you know a workaround for the issue? If yes, please provide a short description -> see above
• Does the issue block your experiments? -> Yes, but we can fix it ourselves.

Hi @Apfelkuchen, your workaround is sensible. I am tempted to adopt it. Thanks!
