HackRF One

This is a rust API for the [HackRF One] software defined radio.

This is not a wrapper around libhackrf, this is a re-implementation of libhackrf in rust, using the [rusb] libusb wrappers.

This is currently in an experimental state, and it is incomplete. For full feature support use the official libhackrf C library.

This is tested only on Linux, but it will likely work on other platforms where libhackrf works.
