Describe your changes

• Implemented a from_cli function and its respective serializer + tests

Related issue/discussion
#290

Extra notes:

• ArgumentParser allows for an auto-generated --help interface, but this not possible in the current implementation. Support for this could be added, but it would require extra top level functions, and I am unsure as to whether that would be overkill or out of scope
• It should be possible to allow from_cli to take 0 arguments, as the internally used parse_args function also allows 0-1 arguments (in case of 0, it takes the arguments passed to the currently running script). However, I don't know if that behaviour is desirable, as it would make from_cli more unlike the other from_* functions
• Technically, to_cli could also be possible (e.g. create a string with the command that would need to be run to get these options), but I don't know if that has much use

@Denperidge thank you very much for this PR!

I see there are some errors on Python 3.8, could you fix them?
I will review this as soon as possible.

[Denperidge]

My pleasure!

Got the error! The exit_on_error option got added in 3.9. But because of the error catching that is done further down, it should be redundant either way.

Take your time to review, and have a nice day!
