Host online documentation

[jonas-schievink]

The build on docs.rs fails because libftdi (understandably) is not installed on the builder. It would be great to still host rustdoc somewhere online.

I have not been feeling well enough to work on this. What would need to be done to get a docs.rs build to work?

FWIW, I have plans to require bindgen/libclang in the future to build, rather than generating a binding that probably only works on x86/amd64 ahead of time.

Looking at libftdi1-sys (which is the actual cause of this issue), you might be able to get away with removing the pkg_config call in the build script for building docs, but I haven't tried that. Perhaps the issue should be filed there.

In any case, get well soon!
