Improve the TCH/H decoder logs
...
- Change "6,90 kbit/s" to "5.9 kbit/s"
A typo reported in github ptrkrysik/gr-gsm#456
- Comment out the "Error! frame_nr:" message as it turns out to confuse
users more then it actually helps debugging.
- When voice-boundary detection is enabled write the name of decoded
control channel messages

Add new TCHH channel mode
Add two new optional arguments
-m CHAN_MODE, --mode=CHAN_MODE
Channel mode. Valid options are 'BCCH' (Non-combined
C0), 'BCCH_SDCCH4'(Combined C0), 'SDCCH8' (Stand-alone
control channel) 'TCHF' (Traffic Channel, Full rate),
'TCHH' (Traffic Channel, Half rate)
--sub-channel=TCH_H_CHANNEL
TCH/H sub-channel. [default=0]
--multi-rate=MULTI_RATE
The MultiRrate configuration element from the
Assigment Command message. Example: 28111a40. See 3GPP
TS 44.018 - 10.5.2.21aa MultiRate configuration
Example:
grgsm_decode -m TCHH --sub-channel 0 --multi-rate 2811 -o voice.amr ...
