Description

This is in response to a discourse question:

https://discourse.julialang.org/t/jumpproblem-hopping-constants-callback/86045?u=robertgregg

Essentially, it would be nice to be able to modify hopping_constants in a callback to simulate a moving boundary separates two regions with different diffusion rates. It sounds like reset_aggregated_jumps! would have to be modified to allow this functionality.

Research direction

Start with the linked Discourse question and inspect reset_aggregated_jumps! to understand how callback updates currently interact with hopping_constants. Reproduce the moving-boundary case described in the issue, then verify that hopping constants can be modified from a callback and that the resulting regions use the intended diffusion rates.
