The scale parameter lambda from the PoissonBernsteinFunction is redundant since the following Bernstein Functions are equivalent:
PoissonBernsteinFunction(lambda = lambda, eta = eta)
ScaledBernsteinFunction(scale = lambda, original = PoissonBernsteinFunction(eta = eta))
Removing lambda will not remove any feature, but will make the user interface more consistent, since most Bernstein function families have a single parameter.
