Add support for file:// URLs to ROME Fetcher

Description

Using ROME Fetcher, I would like to read an RSS file from the file system but
it doesn't seem to be possible. I want to write a test that reads a known RSS
file as test data.

The HTTP fetcher complains if the URL is not an HTTP URL. Perhaps there needs
to be another implementation for file URLs?
