OZ_Mpb, set new bank binding in segment

RST 30H

IN:

     C = memory segment specifier (MS_S0, MS_S1, MS_S2 & MS_S3)
     B = bank number to bind into this segment ($00 - $FF)
OUT, always successful:
     B = bank number previously bound to that segment
Registers changed after return:
     AF.CDEHL/IXIY same
    ..B...../.... different
Notes:

        New API introduced in OZ V4.1
        Bind bank, defined in B, into segment C (MS_Sx). Return old bank binding in B.
        This is the functional equivalent of original OS_MPB, but much faster.
