Auto straighten levelled only by the consensus of long lines, which a sea horizon among waves or
a building's converging verticals don't give. It now tries, in crates/pipeline/src/straighten.rs:
the roll from the vertical vanishing point (at least 8 inliers across the frame), then the
horizon as the straight full-width line with brighter rows on one side (scored by its weaker
columns, so waves, clouds and ridges don't make one), then the long lines as before; the long
lines also veto a horizon they disagree with by more than 1°. The limit drops from 10° to 5°.
Upright Level is unchanged.
On 113 photos straightened by hand in Lightroom Classic: 50 instead of 29 come out straighter,
10 (as before) more tilted, mean error 0.82° instead of 1.01°.
