Description

I'm wondering if you'd be interested in a PR that would allow for solves that are terminated via events to be restarted (after some user-supplied update function is called) until t1 is reached?

This is something very relevant for quantum applications: a typical trajectory can experience multiple events or "jumps" before the final time. If however this is not something you think might be of general interest, happy to implement this outside of diffrax.

Research direction

No files, tests, or entry points are named in the issue. Start by tracing how diffrax handles event-terminated solves and the final time t1; define the scope for a user-supplied update function and repeated restarts, with completion demonstrated by trajectories that continue through multiple events until t1.
