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.

the region.contains() logic is much more expensive than the time bounds
check.

app: multi_core_inverter: de-virtualize the stimuli

this gets like a 5% perf gain.
there are obviously cleaner ways to do it (e.g. use a ListVisitor),
but this is only a proof of concept.
given the low perf difference, i'll likely revert this or explore other
options.

we're diverging from the blog pretty far now.
but it turns out that, because of the inversion in Maxwell's
$\nabla x E = -dB/dT$ equation, the trivial wiring actually leads to
natural inverters.
