Support Ring-Wobble observations / Lower limit of viewcone != 0

Is the use case here "support generating off-axis IRFs from diffuse simulations"?

I can't see a good use case for running sims with viewcones that have a hole in the middle. That's not what's meant by "wobble" observations

The only correct way of simulating point-like gamma-rays for wobble observations I am aware of is using

viewcone_min = view_cone_max = wobble_offset.

producing a ring of source positions.

Is the use case here "support generating off-axis IRFs from diffuse simulations"?
