Users should be able to pass file:// URLs to any of the
sub-commands. In 3be55ed6 the eval and fmt sub-commands were not
updated to accept file:// URLs for the input file and normal paths
(respectively).
This commit just moves the unexported cleanFileURL function from the
loader package into it's own internal package so that it can be shared
in OPA.
