This PR moves the `vfs.py` module, which is only used by plugins, to
avoid polluting the main beets namespace. Also exposes the `vfs` and
`art` module from beets with a deprecation warning.
This commit introduces a `.git-blame-ignore-revs` file to the
repository. The purpose of this file is to list specific commit hashes
that should be ignored when using the `git blame` command. This is
useful for ignoring commits that involve large-scale formatting changes,
refactoring, or other non-functional changes that would otherwise
clutter the blame history.
I added a couple of previous commit hashes which reformatted the code.
Configure this repository to use this file:
git config --local blame.ignoreRevsFile .git-blame-ignore-revs
