memoryFS can't use Pathlike object to ls

[wgqimut]

>>> from fsspec import filesystem
>>> m = filesystem("memory")
>>> m.mkdir("/a/b")
>>> m.ls("/a")
[{'name': '/a/b', 'size': 0, 'type': 'directory'}]
>>> from pathlib import Path
>>> a = Path("/a")
>>> m.ls(a)

I think the memoryFS shouldn't implement it's own _strip_protocol, which is merged by #654 .

As you can see in that PR, there are some peculiarities of memoryFS that require particular coding in _strip_protocol. It should maybe call super()._strip_protocol as part of its call, which may solve this.

However, it's not exactly obvious that Path objects ought to work with non-standard filesystems like memory. I am not strongly against, but I don't see the motivation. Have you tried https://github.com/fsspec/universal_pathlib ?

No I'm not, this repo is great! that's exactly what i'm looking for, thank you so much!
