docs: Create a discount curve from given times and given discount factors using given interpolation and extrapolation methods.
  
  @param name The name of this discount curve.
  @param times Array of times as doubles.
  @param givenDiscountFactors Array of corresponding discount factors.
  @param isParameter Array of booleans specifying whether this point is served "as as parameter", e.g., whether it is calibrates (e.g. using CalibratedCurves).
  @param interpolationMethod The interpolation method used for the curve.
  @param extrapolationMethod The extrapolation method used for the curve.
  @param interpolationEntity The entity interpolated/extrapolated.
  @return A new discount factor object.
