SampleTime histogram data in the JSON output would be nice

Hi,

The SampleTime benchmark mode produce iteration run results like this:

Run result : 
    samples = 6064441
        mean =      0.483 ±(99.9%) 0.002 us/op
         min =      0.000 us/op
  p( 0.0000) =      0.000 us/op
  p(50.0000) =      0.000 us/op
  p(90.0000) =      1.000 us/op
  p(95.0000) =      1.000 us/op
  p(99.0000) =      1.000 us/op
  p(99.9000) =      5.000 us/op
  p(99.9900) =     12.000 us/op
  p(99.9990) =     41.984 us/op
  p(99.9999) =    801.792 us/op
         max =   1077.248 us/op

It would be nice to also have these percentile score lists available in the JSON output. I’ d like to plot them in a chart.

Cheers,
Chris
