Add a user_data column to snapshot table and also a user_data param to create_snapshot so user can pass a Callable to add arbitrary data for comparison (e.g. extended attributes, MD5, etc). The user would then need to pass a compare_function to diff() that would look at this data.

Consolidate create_snapshot and create_snapshot_in_memory by allowing snapshot_db arg to be None. If None, creates in memory.

e.g.

snapshot_on_disk = create_snapshot("/path/to/dir", "dir.snapshot")
snapshot_in_memory = create_snapshot("/path/to/dir", None)

Pass pathlib.Path to compare function to make it easier for user to use a lambda as the function (while getting access to all the Pathlib methods)

Add dirs: bool=True arg to DirDiff().diff() that, if False, skips dirs that change (as dirs will always change if files contained in the dirs changed).

Also add --no-dirs to the CLI to use this option.

Links inside sandbox containers cause an error:

dirsnap --snapshot /Users/rhet/Library/Containers/com.apple.Photos/ checked.db

When encountering this type of link:

Add len to DirSnapshot so len(snapshot) returns count of records in the snaphost
