- LoRaBoard trait now has associated types: RadioParts, CommParts, DisplayParts, DisplayDriver - into_parts() is on the trait (enforced by compiler, not implicit convention) - BoardParts<R, C, D> struct replaces tuple return from into_parts() - mac_address() stays on trait, MAC also in BoardParts for convenience - Removed mac field from DisplayParts (display task calls Board::mac_address()) - DisplayDriver associated type requires DrawTarget<Color = BinaryColor>
