Implement get_batch_metadata

[JackKelly]

The function signature could look something like this:

def PVOutput.get_batch_metadata(
  pv_system_ids,
  output_filename: Optional, # if none provided then just return metadata, don't write to disk 
  overwrite=False # if true then download new metadata, regardless of whether it's in the
                  # HDF file, only relevant of output set
)

do you have the documentation for this?

Is this a seperate API call for this, or does it just look over get_metadata?

I don't remember, sorry!
