Fix internal use of urlparse(x).path to strip file url schemes
This PR modifies two internal uses of urlparse(x).path
to instead use the gwpy.io.utils.file_path
function. Just stripping the scheme out (which is what urlparse(x).path
does) sometimes causes problems on Windows when it gets passes a string with a drive name in it (e.g. C:\Users\me\myfile.txt
). This should have no impact on anybody (except future me).
