    Summary:
    When performing a NIT-scanning of channels all the correct transponders are detected, but not LCN (channel number).
    Area:
    TV-Server (TS-Writer)
    Description:
    However the LCN-value is not found in function
    "CNITDecoder::decodeNITTable" (NITDecoder.cpp),
    causing LCN to a value of 10000 for every channel.

    The descriptor tag 0x83 (Logical Channel Number Descriptor) is processed in code but not 0x87 (Logical Channel Descriptor V2)
    If 0x87 is implemented the channel list can be created automaticly.

    Solution could create channelgroup for every channel list detected.
    Template code:
    Add logic and process 0x87 descriptor tag. in NITDecoder.cpp.
