Add CLI binary installation

[peytondmurray]

This PR adds a configuration setting to install the rust nbstripout-fast CLI to the python binary directory, so that users can easily launch the CLI after installing.

Hmm, looks like we can't yet ship multiple targets with maturin, but that should be something we can do soon. Let me see if we can find a workaround.

One workaround would be to write a python wrapper for the rust CLI :/. Not ideal. Let me see how hard it would be to add multiple targets in maturin.

Yeah, the idea is creating a bin for deploy and python bindings for test. I don't think we need both today.

[peytondmurray]

In that case, I think it makes sense to disable this test for now until the upstream change in maturin to support multiple build targets is merged. What do you think?

Build issues on macos look like they're upstream: PyO3/maturin#1080

Let's disable macos and leave a reference to this issue as a comment?

[mlucool]

@peytondmurray let's try PyO3/maturin#1080 (comment) first?

[peytondmurray]

@mlucool Looks like there's an issue deeper in pyo3 that is blocking our ability to disable the extension-module as suggested in PyO3/maturin#1080 (comment). How do you want to proceed here? I think the quickest thing to do is disable macOS wheel builds for now and add them back when the issue is resolved.

Yeah, let's drop osx for now and cross-link to the issue
