DA14531 SDK Rust bindings

This crate is a wrapper for the manufacturer's SDK. In order to build it, you need to first download the SDK version 6.0.16.1144. In order to compile this crate you need to set the SDK_PATH environment variable to the SDK path, e.g. SDK_PATH=/path/to/my/sdk/6.0.16.1144

Parts of the SDK where completely reimplemented in Rust.

This is highly experimental and still in development at the moment, use with caution!
