Convert CSS inline fonts from woff to otf
This is made to fight non-support for WOFF on PhantomJS (which, even though is supposed to be supported, is not)
const woff2otf = require('convert-css-inline-fonts-woff2otf')
const cssStringWithConvertedFonts = woff2otf(cssStringWithInlineWoffFonts)
Which can now be displayed in any version of PhantomJS
