consider a new output mode for darshan-parser that is more machine parseable
We probably should not change the existing --perf output in case existing analysis tools depend on it, but it would be helpful to have a variation that:
- includes the module name in each line of output (to make it easier to grep)
- only shows what's accepted as the best performance estimate ("by_slowest")
- also outputs bytes
- also outputs time (rate, bytes, and time should all be directly related)
This output mode would probably be preferred for future ML analysis tools.
