* try parallel reduction in batch add, but alas it's slower than custom chunking. Except maybe on arch with performance/efficiency cores
* initial impl of parallel MSM - scaling to debug, threads not woken fast enough
* improve comment [skip ci]
* skip top window when c divides the number of bits
* for some reason parallel-for loops scale on 5+ threads while spawn only on 2x threads. Thread wakeup issue?
* Add counters and timers to audit threadpool bottlenecks
* metrics and profiling fixes, (slower) latency hiding, activate tests
* fix thief thread trying to wake another before canceling its own sleep
* easier to sort metrics and parallel endomorphism application
* selective endomorphism acceleration
* some tuning
* spawn can handle compile-time literals, static and type parameters. Also introduce spawnAwaitable to await void procs
* improve MSM overview [skip ci]
* bench cleanup
* unoptimized msm
* MSM: reorder loops
* add a signed windowed recoding technique
* improve wNAF table access
* use batchAffine
* revamp EC tests
* MSM signed digit support
* refactor MSM: recode signed ahead of time
* missing test vector
* refactor allocs and Alloca sideeffect
* add an endomorphism threshold
* Add Jacobian extended coordinates
* refactor recodings, prepare for parallelizable on-the-fly signed recoding
* recoding changes, introduce proper NAF for pairings
* more pairings refactoring, introduce miller accumulator for EVM
* some optim to the addchain miller loop
* start optimizing multi-pairing
* finish multi-miller loop refactoring
* minor tuning
* MSM: signed encoding suitable for parallelism (no precompute)
* cleanup signed window encoding
* add prefetching
* add metering
* properly init result to infinity
* comment on prefetching
* introduce vartime inversion for batch additions
* fix JacExt infinity conversion
* add batchAffine for MSM, though slower than JacExtended at the moment
* add a batch affine scheduler for MSM
* Add Multi-Scalar-Multiplication endomorphism acceleration
* some tuning
* signed integer fixes + 32-bit + tuning
* Some more tuning
* common msm bench + don't use affine for c < 9
* nit
