flat When applying packed or packed_v2 compression on an array that
treats the entire image as a single line set the maximum number
of bits for an offset to 65 bits.

The flag is included for compatibility with software prior to
CBFlib_0.7.7, and should not be used for new data sets.
uncorrelated_sections When applying packed or packed_v2 compression on an array with
uncorrelated sections, do not average in points from the prior
section.
