Function bezierPath

bezierPath(
    controlPoints: Point[],
    easing: (ti: number) => number,
    renameMe: undefined,
): Point[]
Given a Bézier curve and an easing function, produce a sequence of points suitable for animating the eased movement along the curve. See https://en.wikipedia.org/wiki/Bézier_curve for an explanation of Bézier curves. The easing function must satisfy:
- easing(0) = 0 and easing(1) = 1, so that the interpolation goes from P_0 to P_n
- easing(t) is always in [0, 1], so that the interpolation stays on the curve
Parameters
- controlPoints: Point[]
  Bézier curve control points P_0 through P_n, nonempty
- easing: (ti: number) => number
  function mapping input interpolation parameter ti, 0 <= ti <= 1, to an applied interpolation parameter, as constrained above
- renameMe: undefined
  TODO: you determine the detailed precondition, including a weaker static type
Returns Point[]
TODO: you determine the detailed postcondition, but you may NOT add "throws" cases
