support scaling the display scale of arc segments

[rkyle35242]

Requirements:

1. keep existing implementations intact
2. support a segment value to adjust the size of the arc segments while still supporting segment[].scale

Before/After screenies include the below segments:

  const _segments = [
    {
      scale: 0.94,
      arcDegreeScale: 0.5,
      filledColor: firstSegmentFilledColor,
      emptyColor: firstSegmentEmptyColor,
      data: { label: firstSegmentLabel }
    },
    {
      scale: 0.02,
      arcDegreeScale: 0.3,
      filledColor: secondSegmentFilledColor,
      emptyColor: secondSegmentEmptyColor,
      data: { label: secondSegmentLabel }
    },
    {
      scale: 0.02,
      arcDegreeScale: 0.1,
      filledColor: thirdSegmentFilledColor,
      emptyColor: thirdSegmentEmptyColor,
      data: { label: thirdSegmentLabel }
    },
    {
      scale: 0.02,
      arcDegreeScale: 0.1,
      filledColor: fourthSegmentFilledColor,
      emptyColor: fourthSegmentEmptyColor,
      data: { label: fourthSegmentLabel }
    }
  ];
