WOFF2 on iOS

Today was the first time I got to see WOFF2 on iOS working!

side by side with 9/9 rejecting woff2 Lobster and using the system font for
the 3 woff2 lines

Thanks to Ned for reminding me it only works on specific OS versions (see
https://bug-150830-attachments.webkit.org/attachment.cgi?id=264656) when I
initially thought it wasn't working :)
