CLI: Add -e <cmd> support about bladerf

[smagruder1]

Adding the ability to set the frequency, bandwidth, samplerate, etc. to bladeRF-cli or similar would be a great feature.

For example one might execute "bladeRF-cli -f 350000000 -b 1500000 -s 3000000" to set the frequency to 350 MHz with a bandwidth of 1.5MHz and a sample rate of 3 MHz.

-or-

"bladeRF-cli -f 350000000 -b 1500000 -s 3000000 -config bin -file sample.bin -n 10000" to tune the rx and output samples to a specified file using bin format.

I believe this would streamline the process, improve efficiency and increase user experience.

In the interim, I've written a very basic wrapper script for bladeRF-cli. It currently does not include an argument to specify an output file or format. By default it is set to .csv and samples.csv. Feel free to customize - I'll probably update at a later time along with --help or usage.

NOTE: Currently drops you into interactive mode where all you have to execute is rx start. I've been having difficulties passing this through the script - bladeRF-cli will hang in my case. Feel free to uncomment those lines to give it a shot, and please post your results.

This will help you get started and is as follows:

#!/bin/bash

touch config.txt

while getopts f:b:s:n: option

        case "${option}"
        in
                f) frequency=${OPTARG};;
                b) bandwidth=${OPTARG};;
                s) samplerate=${OPTARG};;
                n) numofsamples=${OPTARG};;
        esac

#echo "exit" >> config.txt

sudo ./bladeRF-cli -s config.txt
#sudo ./bladeRF-cli -s config.txt -b
### MAIN BODY END ###


###CLEAN UP
rm config.txt
echo "Done."

Added as a test thing people can use to test out the bladeRF after install procedure..
