…etty and chart (#98)

* feat: fix whitespace between summaries, extract analysis code
for addition to the other formatters.

* feat: make sorting optional

Feature parity for textReporter, but chartReporter doesn't work this way.

* feat: Report baselines across text, pretty, and chart reporters.

cgroups don't mask off unavailable CPUs and this is considered a
feature not a bug, and so Node got os.availableParallelism() to
attempt to fix this.

This version still has issues (nodejs/node#59200)
but at least it's more likely to be correct.

* chore: run lint:ci on test

* fixup! chore: run lint:ci on test

* chore: Rename analysis file from baseline.js -> analyze.js

Implements #101

* chore: Formatting fixups.
