Unable to save `Config` with `*` args to str/disk

[HLasse]

Hi!

As part of my workflow, I want to save my Config to disk so I can reload it later. However, if the config contains a * section this fails.

Minimal example:

from confection import Config

test_cfg = """[test]
foo = bar

[test.*]
bar = foo
"""

cfg = Config().from_str(test_cfg)

cfg.to_str()

This results in

File "e:\lasse\test\psycop-common\test_confection.py", line 12, in <module>
    cfg.to_str()
  File "E:\ProgramData\Anaconda3\envs\psycop-main\lib\site-packages\confection\__init__.py", line 419, in to_str
    flattened.set(section_name, key, try_dump_json(value, node))
  File "E:\ProgramData\Anaconda3\envs\psycop-main\lib\configparser.py", line 1205, in set
    super().set(section, option, value)
  File "E:\ProgramData\Anaconda3\envs\psycop-main\lib\configparser.py", line 903, in set
    raise NoSectionError(section) from None
configparser.NoSectionError: No section: 'test.*'

Tested on Windows and MacOS, using confection 0.1.3 and 0.1.4

Converting it to [test.*.value] solves the issue.

However unsure if that is the desired functionality. If it is it might be worth adding a check to see if any section ends with a * if it isn't the desired functionality.

Yea, I think that's probably the best solution for now
