Output all char-sequences needed for a language

@EbenSorkin My recent immersion in Emoji reminds me that, just because Unicode does not define codepoints for these "standard" yet unencoded glyphs, does not mean they shouldn’t be responsible for maintaining a list of them. And that list can be imported into Glyphs etc., just as the Emoji sequence definitions can be imported into font editors and glyph pickers.

I think this belongs as a shaperglot feature; an arg to output all the chars and char-sequences needed for a language that has a shaperglot profile

@davelab6 shaperglot already does this:

To test for Yoruba support, shaperglot will:
