[css-font-loading] [info discovery] MATH table

[litherum]

From #520 (comment): It might make sense to expose MATH table data.

I actually don't think we should do this, because there is no CSS property to feed this data to. This data is only useful if you're implementing a MathML renderer in JS, which you shouldn't be doing, you should just be using MathML directly instead.

I'm actually implementing a Latex renderer in JS. This has nothing to do with MathML. And there could be many other reasons to want to access those tables. They are included in the font file for a reason.
