Add benchmarks using streaming parser

[skjolber]

I would prefer comparing the performance to the streaming apis of the competing parsers (i.e. jacksons and so), instead of first mapping to objects. At least for the simpler benchmarks, this would be more fair.

JsonSurfer is built upon those streaming api, not really competing with them

I concur @skjolber. Such benchmarks would illustrate the costs of JsonPath filtering
