Vasil Velichkov 5968552b47 Add TCH/H decoder block with AMR multirate support 
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 ...

Piotr Krysik 773a194c32 Big change of the universal control channels demapper: 
-simplification of the universal demapper,
-addition of hierarhical blocks for each of the demappers - so they also look well and readable in python,
-addition of helper script for compilation of the demappers.
