oauth errors with TypeError

[Sebastian Schauenburg]

when using offlineimap(3) to sync (in my case gmail) with oauth, it errors with the following:

Traceback (most recent call last):
  File "/usr/share/offlineimap3/offlineimap/threadutil.py", line 146, in run

    refresh_token = refresh_token.strip("\n")
TypeError: a bytes-like object is required, not 'str'

It was also reported upstream and fixed there recently (August 3rd): https://github.com/OfflineIMAP/offlineimap3/issues/57

Looking at the package version number ( 0.0~git20210225.1e7ef9e+dfsg-4 ), it dates from February 2021. I assume updating the package to a more recent version will fix this issue.
