Replaced Path* dataclasses with PathInfo/URLInfo/CloudURLInfo, which
know how parse, serialize, stringify and join themselves. They also
provide useful accessors like part of an url or pathlib.Path like
.parent or .name.
Along the way two families of bugs where fixed and should never occur in
the future:
- paths not matched as strings anymore, e.g. using str.startswith()
- Output.path is eliminated as ambiguous
Both families might had caused undefined surprising behavior when local
and remote paths clash.
