How to set survey metadata values for v0.1.0 data

[kkappler]

I added a test to tests/version_1/test_mth5.py

    def test_set_survey_metadata(self):
        """ Test that we can change a value in the survey metadata and this is written to mth5"""
        survey_metadata = self.mth5_obj.survey_group.metadata
        assert survey_metadata.id is None
        new_survey_id = "MT Survey"
        survey_metadata.id = new_survey_id
        assert survey_metadata.id == new_survey_id
        self.mth5_obj.survey_group.metadata = survey_metadata
        assert self.mth5_obj.survey_group.metadata.id == new_survey_id

The last line fails and I'm not sure why. This sort of setting seems to work in v0.2.0, but the syntax is different.

Actually, the solution was to use

self.mth5_obj.survey_group.update_metadata(survey_metadata.to_dict())
assert self.mth5_obj.survey_group.metadata.id == new_survey_id

as the last two lines. I'll commit this test for future reference

test is on branch fix_issue_219. When that is merged into main this can be closed.
