Auxiliar function for hyper Poisson
This function is used inside density function of Hyper Poisson.
F11(z, c, maxiter_series = 10000, tol = 1e-10)
z, c
: values for F11.maxiter_series
: maximum value to obtain F11.tol
: this is the tolerance of the infinite sum.returns the value for the F11 function.
