    fake_trx: implement a new tool for TRX protocol sniffing
    This change introduces a new tool, which could be used to sniff a
    single connection between L1 and TRX in both directions, filter
    captured bursts by direction, timeslot and/or frame number, and
    finally write them to a binary file for further analysis.
    Sniffing capability is based on Scapy framework, so it should
    be installed in order to run this tool. Please also note,
    that sniffing requires root access. For details, see:
    Usage example:
      sudo ./trx_sniff --frame-count 30 --timeslot 2 -o /tmp/bursts
    This command will capture 30 frames on timeslot number 2, and
    write them to a binary file. The format of this file is based
    on TLV (Tag Length Value), that wraps each burst:
      ... |-TAG (byte)-|-LEN (byte)-|-BURST (LEN bytes)-| ...
      TAG 0x01 - a message coming from L1 to TRX
      TAG 0x02 - a message coming from TRX to L1
