  [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
