Xaux release 0.3.4

What's Changed

• Added method argument to copy and move functions, to allow forcing xrdcp, eoscmd, or mount.

Development updates

• Updated poetry api in pyproject.toml to latest
• Important bugfix: after adding __eq__ to FsPath in a previous release, it automatically got __hash__ = None assigned to the class __dict__, which made it unhashable (and hence made .glob() and .rglob() fail).
• Removed numpy and pandas dependencies; now xaux only depends on the standard library.
