[woff2] Remove sfnt size guess check In WOFF the `totalSfntSize` must be correct, however in WOFF2 this value is now just a hint and a conforming implementation must not reject otherwise valid data if the `totalSfntSize` turns out not to be exact. * src/sfnt/sfwoff2.c (woff2_open_font): remove check that uncompressed woff2 data would fit in the sfnt size guess. Fixes: #1235
