Cariboulite CLI issues

[itamarstarbird]

Hey, if it's possible, I'd like to suggest the following functionality that will make it much easier to use the Cariboulite in the simplest way in scripts, without having to struggle with GNU/Soapy API.

cariboulite_util -d "$DEVICE" -f "$FREQUENCY" -n "$NUM_SAMPLES" -s "$SAMPLE_RATE" -F CF32 - > "$FILENAME"

This should output the files in .iq format on complex32.

I know the cariboulite_util exists but I couldn't get it to function like that.
I have used the rx_tools that uses Soapy API, but then I've gotten some weird decimation in all sample rates.
