feat(reason-skia): bind to `FontMetrics` char width functions #904

Closed zbaylin closed 4 years ago

This is a really small change that just adds two functions from FontMetrics: the average character width and the maximum character width. These functions make it easy to test if a loaded font is monospace through

FontMetrics.avgCharacterWidth(metrics) == FontMetrics.maxCharacaterWidth(metrics)

I tested this with Consolas and it worked. Fortunately it also worked with FiraCode (I was worried that maybe the ligatures would register strangely).
