Incorrectly name flair align options is confusing

[diekhans]

flair align has this option

parser.add_argument('-N', '--keep_supplementary', type=int, default=0,
        help='retain at most INT secondary alignments from minimap2 alignment (default 0)')

--keep_supplementary is a head-exploding name because this keeps secondary alignments. Supplementary alignments are not the same as secondary alignments.
