UnhandledProtocolError: This implementation only supports s2k. Server returned s2k_fo

When I provide my email and password as requested by real_airtag.py I get the following trace and I have no idea what went wrong and how to fix it:

Traceback (most recent call last):
  File "C:\python-files\airtag\_login.py", line 77, in get_account_sync
    with acc_store.open() as f:
  File "C:\programs\Python310\lib\pathlib.py", line 1119, in open
    return self._accessor.open(self, mode, buffering, encoding, errors,
FileNotFoundError: [Errno 2] No such file or directory: 'account.json'

During handling of the above exception, another exception occurred:

I figured out how to support s2k_fo and will provide a pull request probably this weekend.

That would be fantastic, I'm gonna be quite busy for the next week or so, but if you provide a pr I'll try to look at it asap.

I'm guessing Apple updated the authentication method for some reason, I wonder if it differs per account?
