Documentation failing to build for docs.rs

[mitchmindtree]

Despite specifying the macos target for documentation to build in our Cargo.toml, the build will still fail when building for docs.rs. This is because docs.rs attempts to build for macOS via cross-compilation from Linux. This should be first solved in coreaudio-sys before attempting to fix coreaudio-rs.

I had similar issue with a crate for windows, where I simply worked around the problem by hosting the docs on GitHub pages instead. See https://henquist.github.io/wasapi-rs/
The docs are built from the "docs" branch of the repo.
Would that be an acceptable solution here too?
