limesdr: add ability to select RX channel 

Add ability to select an RX channel by number. By default channel 0 is
used.

Test: connect LimeSDR device and try to select the RX channel by number:
    OK: $ ./dump1090 --device-type limesdr --limesdr-channel 0
    OK: $ ./dump1090 --device-type limesdr --limesdr-channel 1
    NG: $ ./dump1090 --device-type limesdr --limesdr-channel 2
        $ limesdr: Invalid channel number.
