Path snapshotting support

[noirbizarre]

Is your feature request related to a problem? Please describe.

I would love to be able to make path snapshots and being able to write:

def test_something(snapshot):
	path: Path = do_something()
    assert path == snapshot

Would you be open to a pull request bringing this feature ? Because I have one which is working just fine, covered in test...

This includes:

• both file and directory support
• support both filtering and matching
• proper diff with syntax highlighting using the same pattern as pytest (aka. support pygments as optional, so failsafe if it is not present)

Here's a sample syntax highlighted output:

Describe the solution you'd like

Describe alternatives you've considered

Alternative: publish it separately, like an extension to the extension, something like syrupy-path. But I thought directory/file snapshotting is so common that it would make more sense to have this in syrupy

Additional context

Sorry to present it like that. In fact, I crafted my PR and then when rereading the contribution guide, I noticed this paragraph so here I am.

Adding improved support for Path would be welcome! Feel free to open a pull request if you already have a proposed change.

@noirbizarre Is this something you're still interested in? If so, contributions are welcome

[noirbizarre]

Yes, it is.
Actually, I have an (unpublished) yet repository with it, but I faced some difficulties as all types, all mechanics (especially snapshot discovery) are meant for a single file, and breaks with a directory.
I'll publish as soon as possible to discuss what would be possible, what should be done, and whether it still belongs here or not.
