hackrf: add support for HackRF devices through libhackrf
features: - gain control for LNA & VGA - frequency error correction - automatic baseband filter - up to 20M sampling rate limitations: - no DC offset correction implemented (yet) - no RX preamplifier control (disabled by default) - high sampling rates may not work on slow machinesgr3.6
