Sub-millisecond profiling for python pstats

A simple monkeypath for the pstats module to be able to see sub-millisecond timings

If display value is 0.000, display the time in microseconds

Thanks for your sharing nice information!

Thanks for the code, but it seems that you have one excess zero in the multiplier "10000000".

In fact 2447µs would mean 0.002 seconds, which is not sub-millisecond
