fn kambe_arguments(value: Complex, w: Complex) -> (Complex, Complex)
The argument x = sqrt(-2 v) w (Re x >= 0) and split eta = -i / w of the Kambe integrals with F_n(v, w^2) = 2 I_(2n-1)(x, eta) w^2n, for Re w >= 0.
x = sqrt(-2 v) w
Re x >= 0
eta = -i / w
F_n(v, w^2) = 2 I_(2n-1)(x, eta) w^2n
Re w >= 0
