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 nusb user-space rust library.

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.

USB user-space access

Adapted from nusb-linux-setup.
This is only needed if you want to run as non-root user, although the initial setup does require sudo.

1. # Create a `udev` rule
   echo 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="1d50", ATTRS{idProduct}=="6089", MODE="0660", GROUP="hackrfone"' | sudo tee /etc/udev/rules.d/99-hackrfone-usb.rules

2. # Add current user to group
   sudo groupadd hackrfone
   sudo usermod -aG hackrfone $USER

3. Best to restart the system now so new group shows up and device is mapped correctly
