Driver: stimulus: use our own JobPool abstraction
...
this one leverages crossbeam.
it does appear to schedule jobs faster than the rust-threadpool.
curiously, the `recv` impl seems to be slower.
maybe that's because of the (inadvertent, unecessary) switch from mpsc
to mppc. worth trying to just insert a buffer.

driver: implement an optimized stimulus adapter over ModulatedVectorField

this boosts perf from 520fps -> 632fps.
it does some uneccessary clones.
but it looks like the bulk of the inefficiency resides inside
the sim/spirv/ code though.
it might be that this is nearly memory-bottlenecked.
if so, backgrounding it might be sensible.
