Get mudslide ready for excited-state QM/MM simulations.

One of the challenges is that Turbomole currently only computes point charge forces from a single electronic density. That means QM/MM can only run in a mode where only one excited-state force is computed at a time. Thus, mudslide needs to be extended to pass the active state to the model.

• QM/MM for the ground state
• pass active state information to model.compute() function through one of the keyword arguments
• update $exopt datagroup to compute the correct state
• keep track of which excited-state is being computed when populating model._force
• check that excited-state forces include point charge terms by finite difference
