Regenerate JST Single-row-with-MP footprints
This is a straight regeneration of the JST single-row with mounting pad families.
Very many of these have been wrong for ages, because they weren't regenerated after kicad-footprint-generator@f2b13dd7 in 2018 which fixed the incorrect mapping of the orientations, as reported in #2582 (closed).
Marking as draft until I can check the diffs better, but please comment!
As best as I can tell, these haven't changed in geometry.
