Kip RickerandFacebook Github Bot cfeaefb4e0 iOS: Fix font weight resolution 
Summary:
**Issue:**
Some fonts are defined with weights that don't match with the UIFontWeight constants.

**Example:**
UIFontWeightTraits for Roboto font
Light: -0.230
Thin: -0.365

Currently, the UIFontWeightTrait is always used if it != 0.0, and given the UIFontWeight constants for Light and Thin:
UIFontWeightThin -0.6
UIFontWeightLight -0.4

A style font weight of "300" or "200" will both resolve to Roboto-Thin as its weight -0.365 is closer to -0.4 (UIFontWeightLight) and -0.6 (UIFontWeightThin) than -0.230 (Roboto-Light).

**Proposed fix:**
When resolving `getWeightOfFont` try to match the name of weight to the name of the font first, and guess the font with UIFontWeightTrait as the fall back.

**Test Plan:**
Attempt to display Roboto at weights "200" and "300" and Roboto-Thin and Roboto-Light should be displayed correctly.
