cmd/benchseries: a fresh start commit, because git/gerrit got mad at the old one

This is a squash of all that work, applied using patch.
Testdata in a bit, I intend to rework that.

split defaults into real defaults and bent defaults.
document the defaults
normalize all the times flowing through to UTC.
update time normalization to allow nanosecond time stamps.
add change detection for no-noise benchmarks
tinker around the edges for MK
fixed to be robust with mixed old/new (old = summaries from JSON, DB )
collects residues, per-unit.

The bent defaults ignore a lot of keys to avoid dealing with dirty bent data.

It now has a test of repeatable behavior and order independence.
A few more functions in benchseries have been exported, I added
a convenience function for reading benchmark files.

The floating point code was tweaked to work the same on arm64
and other architectures with fused multiply-add.
