External stage cost integration methods

Hi!

I’m using acados through the Python interface, and as I understand it, only explicit Euler is currently supported for integration of the external stage cost. For my application, I would like to use the same IRK/GNSF integrator as the one I use for the system dynamics, by applying the quadrature rule.

Could this be a possible next feature? Thanks for your consideration!

Cheers,
Jochem
