* Extended functionality is gated on an "unstable" feature
* Designed for very simple use and minimal interferance with existing legacy implementation
* Intended to be temporary, until bumble can integrate extended advertising into its core functionality
* Dropped `HciCommandWrapper` in favor of using bumble's `HCI_Command.from_bytes` for converting from PDL into bumble implementation
* Refactored Address and Device constructors to better match what the python constructors expect
* Autogenerate packet code in Rust from PDL (packet file copied from rootcanal)
* Implement parsing of packets that have a type header
* Expose Python APIs for sending HCI commands
* Expose Python APIs for instantiating a local controller
