    EVS: Handle A.2.1.3 Special case for 56 bit payload size
    
    The resulting ambiguity between EVS Primary 2.8 kbps and EVS AMR-WB IO
    SID frames is resolved through the
    most significant bit (MSB) of the first byte of the payload. By
    definition, the first data bit d(0) of the EVS Primary 2.8
    kbps is always set to 0. Therefore, if the MSB of the first
    byte of the payload is set to 0 (see Figure A.2), then the
    payload is an EVS Primary 2.8 kbps frame in Compact format. Otherwise it
    is an EVS AMR-WB IO SID frame in
    Header-Full format with one CMR byte.
