template_dir and importlib/pkg_resources

[pvgenuchten]

Currently the template_dir to a custom schema implementation requires a phisical path on disk
It would be nice if pygeometa would also be able to leverage packaged resources either with importlib or pkg_resources?
any thoughts on this?

@pvgenuchten does this mean being able to implement a schema via a Python class/factory pattern? i.e.:

xml_string = render_j2_template(mcf_dict, schema_local=my_package.my_module.my_file.MyClass)
