Easy Enhancement: filepath instead of filename for pyro.render_model()

[LysSanzMoreta]

Hi!

I am just wondering if it would be possible to have a small fix to the pyro.render_model() function, so that it can take a filepath instead of a filename to save the .pdf to. Right now the function removes the path from the name (not sure why):

    if filename is not None:
        filename = Path(filename)
        suffix = filename.suffix[1:]  # remove leading period from suffix
        graph.render(filename.stem, view=False, cleanup=True, format=suffix)

Thanks!

Keeping the path sounds more reasonable to me. Do you want to submit the change?
