Radical variant information

[wisnij]

The table of radicals on https://kanjialive.com/214-traditional-kanji-radicals includes "a variant of..." links to the main or full-size kanji that a smaller radical derives from, but I don't see that information in the data files here. Could it be added to these data files, particularly japanese-radicals.csv? This would be very useful for grouping them, such as for displaying all the variants of a particular radical side-by-side.

(I'm guessing that could be derived implicitly from the ordering in the current version of the file, i.e. all the contiguous entries with the same Meaning are variants of the first one, but it would be nice to have it expressed in the data more explicitly.)

Perhaps a Variant-Of field giving the Radical ID# value of the corresponding entry, e.g.:

Radical ID#,Stroke#,Radical,Meaning,Reading-J,Reading-R,R-Filename,Anim-Filename,Position-J,Position-R,Variant-Of
...
6,1,⼄,the second ,おつ,otsu,otsu-nine,otsu,,,
7,1,⺃,the second,おつ,otsu,,,,,6
...

EDIT: While I think of it, the "Importance" column would also be useful information to have.
