Give the disc sizes the framing quotes as radii, and the meta columns in the order they are stored

The framing rule works in radii: at 390x844 a giant's disc may take 0.74 - 90/195 = 0.278 of the
195 px half-side, 54 px from the centre, and before e62e2fb it took half of it, 98 px. The comment
and the spec called the 98 px a disc, which reads as a width, and a name 70 px from the centre
would then have been off it. e62e2fb's message says "54 px wide" and "98 px wide" for the same
radii: the discs are about 108 and 195 px across.

The stars-meta.bin doc comment still put the photometry byte before the distance error, which
f31ffe1 moved ahead of it for alignment; metaColumns, the DISTANCE_ERROR_STEPS comment and the
README already had the new order.

The scene's 2 883 hosts past the survey edge are all hosts past it: 2 878 are the archive's own
stars and 5 are HYG's (HD 81817, HD 102272, HD 158996, HD 208527, HD 220074).
