Bug description:
When running auto_align_stack or doing any pairwise control-point generation of
an HDR sequence, it makes a huge difference to order the pairing by sequential
exposures. Autobracket sequences are often stored as a seqence with
increasing difference from 0 exposure compensation alternating with under and
over exposed frames. If you then optimize in that order you end up matching a
heavily under-exposed frame with an heavily-over-exposed one resulting in poor
control point generation. By ordering them from least to most exposed, the
pairs are the most similar.
