New API call introduced in and used by OZ V4.1 and newer for fastest bank switching functionality possible.
Get current Bank binding for specified segment MS_Sx, defined in C. This is the functional equivalent of OS_Mgb and the OS_Fc, but much faster, since there is no system call decoding overhead. The routine resides in LOWRAM.
