Feature Request: scoreFontWeight

[awatson1978]

Request from the design team to decrease the font weight of the hScore in the center. We currently have scoreFontSize and scoreFontColor, but no ability to control for font weight.

          <HGraph
            data={ data.currentData }
            width={ graphSize }
            height={ graphSize }
            score={ 42 }
            scoreFontSize={ graphSize < 300 ? 48 : 96 }
            scoreFontWeight={ 200 }
          />
