Getting "x is not one of the valid .xml types" when using Reader.get_mff_contents

[jbteves]

When using mffpy.Reader class and get_mff_contents(), I receive the following message:

'{http://www.egi.com/pnsSet_mff}PNSSet' is not one of the valid .xml types
'mriInfo' is not one of the valid .xml types
'workspace' is not one of the valid .xml types
'workspace' is not one of the valid .xml types
'date' is not one of the valid .xml types

I'm not sure what the source of this error is, this comes from a standard MFF file being acquired in tandem with MRI data.

@jbteves, we have parsers for several (but not all) possible XML types in an MFF https://github.com/BEL-Public/mffpy/blob/develop/mffpy/xml_files.py.

We would like to eventually add parsers for all MFF XML types and we invite outside contributions of new XML parsers.
