5286339413 app: stacked-cores: 40xx db: preserve parameterization in more context
i want to add some filtering functions to the db lookups, and this will
faciliate that

162e9630ad try dumb vertical scaling of inverters
it seems that if we take a non-inverter than has y(0) *close* to 0, and
scale it enough, then we get stable transfer.

this suggests we really just want something with a massive number of
couplings (to keep the coupling ideal) and enough asymmetric windings to
get us > 1.0 tx ratio over some range.

83bd15673d app: stacked cores: record more 40-xx runs
notably, these are entirely new:
`40-0.0008rad-18coupling-5_1_winding-5e10-drive-xx`

2eb714ff74 app: stacked_cores: ingest more runs
the larger cores may indeed be doing better (a little early to tell).
the tendency right now is that too much transfer occurs too early,
such that the region of > 1.0 slope maps _outside_ that region, not
allowing for an inverter to work well.

a3d9b28ab6 capture high-level GPU timing diagnostics
this shows that we spend about 2/3 of the GPU roundtrip time on
stepping. the other 1/3 is i guess scheduling/latency/memory transfers.

1387506511 try printing out gpu timesteps
this seems to just print all 0 on my laptop.
maybe it'll work better on a newer GPU.
following the example in Embark's rust-gpu:

638a97c106 app: stacked-cores: short-circuit sims that have already completed
this takes the per-sim time down from about 30s to 1s for completed
runs. allows much easier stopping + restarting of batched sims.

6e32f9791e app: stacked_cores: re-analyze 17-xx and 18-xx fork-and-join experiments
neither of these produce good amplification.
- we expect bad amplification for 18-xx because it doesn't do any loops
  with > 2 cores
- 17-xx might just need reduced drive current
