Function pseudoVoigtDerivative

pseudoVoigtDerivative(
    x: number,
    fwhm: number,
    mu: number,
): { dFwhm: number; dMu: number; dx: number; fct: number }
Analytical value and partial derivatives of the pseudo-Voigt function centered at x=0.
Parameters
- x: number
  position at which to evaluate.
- fwhm: number
  full width at half maximum.
- mu: number
  ratio of gaussian contribution in the shape.
Returns { dFwhm: number; dMu: number; dx: number; fct: number }
the value fct and its partial derivatives with respect to x (dx), fwhm (dFwhm) and mu (dMu).
