Add support for OTF fonts

They're not currently supported, are they? At least in my tests only TTF fonts are loading properly. Is it possible to do? :) Thanks!

yep, you are right; fontStash only supports TT fonts... you can convert an OTF to TTF though!

there's a new version of fontStash that supports that, but it changes quite radically and it looks like it would be an involved update
