Driver crates

Platform agnostic crates to interface external components. These crates use the embedded-hal interface to support all the devices and systems that implement the embedded-hal traits.

The list below contains drivers that have achieved the "released" status. In order to add a driver to this list, please ensure that your driver has a short blog post, article or sufficiently explanatory README showing an example of its use. Ideally this post would demonstrate using the device in a small project so that a Rust and/or embedded newcomer can also understand it. Otherwise please add it to the WIP section below.
