Fatest JSON Python module

Run Python JSON benchmarks to find the fastest module that can be used as a drop-in replacement of the json standard one.

Benchmarks are run from a GitHub workflow.

See the requirements.txt file for exact modules being tested, and which imports are being used in the benchmark script.
