README's "for ... library from Google" text could be confusing?

The python-snappy README and PyPI project description for python-snappy currently say this as their headline:

README:

> Python library for the snappy compression library from Google.

PyPI [page](https://pypi.org/project/python-snappy/):

> Python bindings for the snappy compression library from Google.
>
> More details about Snappy library: [http://google.github.io/snappy](http://google.github.io/snappy)

I found this a little confusing when I was trying to figure out python-snappy's dependencies. Especially with the link on the PyPI page going to libsnappy.

python-snappy implements the snappy compression _protocol_ from Google. To me, "the snappy compression _library_ from Google" means the "libsnappy" native/C library Google publishes. (At the [google/snappy repo](https://github.com/google/snappy), and packaged as the [`snappy` conda-forge package](https://anaconda.org/channels/conda-forge/packages/snappy/overview) and libsnappy-* apt packages in Ubuntu etc.). But since https://github.com/intake/python-snappy/pull/130 and python-snappy 0.7.0 or so in Feb 2024, python-snappy uses cramjam instead of libsnappy. (Right?)

Maybe these should say "Python library for the snappy compression _protocol_ from Google" instead? Or "format"? But not "library".

And maybe this thing at the bottom of the README should clarify that it's being used as a reference for the protocol etc., and the implementation library itself is not a dependency or part of python-snappy.

Start with the README headline and the project metadata that supplies the PyPI description, then verify the distinction between python-snappy's Snappy protocol implementation and the native libsnappy library referenced by the links. Update both descriptions and the README's closing explanation so the dependency and reference relationship is unambiguous.
