tools: Add tool to analyze settling time of gain of freq changes
This tool uses the Python API to acquire a snapshot of samples during
a gain or frequency change. It can be used to analyze the settling time
of analog components, as well as the accuracy in time.
It has two combinable ways of analyzing the data: 1) Write it to a file,
or 2) plot the time-domain data.
Example: This would receive several seconds of data from an X3x0 device,
tune to 1 GHz, and then bump the gain by 30 dB after a set amount of
time:
$ rx_settling_time.py -a type=x300 -f 1e9 -g 0 --new-gain 30 --plot
