Refactored GPIO module

Browse Source 
- The GPIO module uses type-level programming now
- Implementation heavily based on the ATSAMD GPIO HAL:
  https://docs.rs/atsamd-hal/0.13.0/atsamd_hal/gpio/v2/index.html
- Changes to API, but no passing of peripheral references necessary
  anymore. All examples and tests updated accordingly
