[PATCH] osmocom-bb[master]: fake_trx/data_msg.py: implement header description

[Harald Welte]

Review at  https://gerrit.osmocom.org/6826

fake_trx/data_msg.py: implement header description

This change introduces a new method for both types of messages
called 'desc_hdr', that generates human-readable header
description.

Examples:

  TRX -> L1: fn=571353 tn=1 rssi=-108 toa=-0.53
  L1 -> TRX: fn=1777477 tn=3 pwr=161
