George Burgess IV 75b5718d20 nanobench: Add per-run time reporting. 
This patch adds per-benchmark-iteration times to our JSON output. Given that we
already collect these statistics, giving them to the user would be nice.

No unit-test provided, since `rgrep -i json tests` yielded nothing. Happy to add
one if someone wants.

BUG=None.
TEST=nanobench now writes per-run timinings with the output JSON.

// the image. For that reason, we will benchmark decodes in five representative locations
// in the image. Additionally, this use case utilizes power of two scaling, so we will
// test on power of two sample sizes. The output tile is always 512x512, so, when a
// sampleSize is used, the size of the subset that is decoded is always
// (sampleSize*512)x(sampleSize*512).
// There are a few good reasons to only test on power of two sample sizes at this time:
// All use cases we are aware of only scale by powers of two.
// PNG decodes use the indicated sampling strategy regardless of the sample size, so
// these tests are sufficient to provide good coverage of our scaling options.
