ActivitiesType incomplete?

The _process_activities() method in the LogbookServiceClient supports passing the activities as strings:

https://gitlab.cern.ch/scripting-tools/pylogbook/-/blob/master/pylogbook/_low_level_client.py#L242

But this is not exposed in the high-level Client:

https://gitlab.cern.ch/scripting-tools/pylogbook/-/blob/master/pylogbook/_client.py#L67

Nor in the ActivitiesType definition:

https://gitlab.cern.ch/scripting-tools/pylogbook/-/blob/master/pylogbook/_activity_names.py#L16

Although if you pass a string it does work...

Actually I am not sure why the _convert_to_activities_ids() method of the Client is needed as the same processing is re-done in the LogbookServiceClient.
