Storing session data in `./garmin_session` breaks for non-root K8s deployments

[ethanbergstrom]

The K8s examples explicitly do not run as root, but the current implementation of Garth post-v4 upgrade puts ./garmin_session in /, which is a location a non-root user wouldn't normally be able to write to.

Looks like this should be fixed in #144 in that it now derives its path from $HOME the same way Withings session data is stored, but wanted to call this out as a separate but related issue.

Working around it for now by specifying workingDir in my K8s job to match the same directory as $HOME.

Fixed with v4.2.0

Any idea of when this fix will be released in PyPi? I'm configuring this syncer for my home server where I'd like to run this as a non-root user and it looks like this prevents me from running the script:

Traceback (most recent call last):
  File "/home/syncer/.local/lib/python3.9/site-packages/withings_sync/garmin.py", line 38, in get_session
    garth.save('./garmin_session')

    mkdir(name, mode)

During handling of the above exception, another exception occurred:
