spi-hal

Previously known as embedded-spi, new releases at crates.io/crates/spi-hal. A helper package for rust-embedded SPI traits and implementations, including testing approactes prior to proposing additions to embedded-hal.

This provides:

• A Transactional SPI interface (https://github.com/rust-embedded/embedded-hal/pull/191)
• A CS pin trait to communicate CS control for drivers
• a Wrapper type to provide this for an SPI and OutputPin implementation
• a Hal that abstracts over a number of SPI implementations to assist with writing driver utilities
• a Mock helper for testing drivers based on this
• a set of compatibility shims for c FFI use with dependency injected drivers
