HAL for working with atsamd devices

This crate provides a type-safe API for working with atsamd21 and atsamd51 based devices. Currently this crate supports atsamd21g18a, atsamd21e18a or atsamd51j19a (selectable via the samd21g18a, samd21e18a, or samd51j19a features), and should be able to support other variants in a similar fashion; pull requests for this are welcomed!
