[fontless] support generating only woff2 formats without woff #659
Description
🆒 Your use case
As noted in #657, unifont google provider includes both woff2 and woff with overlapping font data. For many application targeting modern browser, only woff2 is necessary.
Related to #658, with current single hard-coded font, this is less noticable, but when requesting multiple weight range, it looks like meta.priority: 1 version cannot return variable fonts (perhaps because google returns non variable font for old user agent) and it causes downloading a lot more unnecessary font files for each weight.
🆕 The solution you'd like
Use only fonts with meta.priority: 0 on fontless side by default.
