Subject: [PATCH] perf: standardize uri_escape_unescape benchmark
Two new options are introduced:
* The `--output` option allows you to specify the output file.
* The `--output_format` option means the format for the printed output.
The default is "console". It just prints the amount of iterations
proceeded per second to the stdout. The "json" format contains all the
information about the benchmark in a format similar to Google
Benchmark's.
Usually, these options should be used together to dump machine-readable
results for the benchmarks.
