Add Benchmarks

[IvanIsCoding]

What is the expected enhancement?

It would be nice to have benchmarks of celq against:

1. jq
2. jaq
3. fastgron (https://github.com/adamritter/fastgron)
4. jsongrep ( https://github.com/micahkepe/jsongrep)

To quantify how much slower or faster celq is compared to other tools.
