Invert the bit packing order on SP data


Invert the bit packing order on SP data. Normally bits are little endian ordered.
The first sample is in bit=0, second in bit=1 ... bit=7.  With the BIGEND flag, the
first sample is bit=7, second sample is bit=6, ... bit=0.  When running under X-Midas,
the default bit-packing is BIGEND.  Under NeXtMidas and non-Midas, the default is 
little endian.
