How do we know what parts are the filename? The colon separates the scheme
from the rest of the uri, so we cannot know whether a colon in a name delimits
the scheme or part of the name.
> Also, we probably should provide a option to allow user giving a raw URI.
We only support a subset of URIs, so we need to have our own constructors to
validate and normalize. We could accept a URI and check that it is of the form
we require. The easiest implementation would be to convert it to a string and
pass it to the existing constructor. What's the use case?
