Add CLI to register time series
Add CLI wrapper around this function: https://github.com/EOxServer/eoxserver/blob/master/eoxserver/resources/coverages/registration/zarr.py#L201
The CLI command should be done in here: https://github.com/EOxServer/eoxserver/tree/master/eoxserver/resources/coverages/management/commands using the same style of command as the other commands in that directory.
