mini benchmark on extracting field from JSON string

json_mini_bench.go

//With the updated json parsing as of May 8, 2017, the speed of extraction from JSON string increased more than twice:
//using old API it took 7.2 seconds, with new API, it took 2.3 sec)
//the new API allows decoding JSON with a sequence of field names to specify the element to be extracted.
