Parse out URL parameters

[pjbull]

Some URIs passed to us may have query parameters and other annoying URL cruft (e.g., s3://bucket/a?presign=abc or something like that). We should be able to use urllib parse to segment these out from the path since we already generate the parsed URL version: https://github.com/drivendataorg/cloudpathlib/blob/master/cloudpathlib/cloudpath.py#L48
