Variable font support

[Pepite-Atelier]

Hi Kontur,

Firstly, thanks for your incredible work !
I know that this is a subject that was discussed a year ago, is it possible to add to the wordpress plugin the management of variable fonts like on the version standalone webfont type tester https://github.com/underscoretype/fontsampler-js ? We are creating more and more variable fonts, it would be wonderful.

Thanks for your time,
Pepite
