More advanced timing loggers.
The new timing loggers have lower overhead since they only push into
a vector. The new format has two types, a start timing and a stop
timing. You can thing of these as brackets associated with a
timestamp. It uses these to construct various statistics when needed,
such as: Total time, exclusive time, and nesting depth.
Changed PrettyDuration to have a default of 3 digits after the decimal
point.
Exaple of a GC dump with exclusive / total times and indenting:
