Move to simdjson praser

[mkalioby]

Hi,

Thanks for the great library, I'm using this since 2015.

I'm suggesting to change the JSON praser to simdjson (https://github.com/simdjson/simdjson) as it is much faster (based on stats on the repo), the library has a python binding (https://github.com/TkTech/pysimdjson), so can you tell me the feasibility of doing so? and i can help of you like.

Thanks for the great library again.

Hi @mkalioby. Changing the default json implementation won't happen (compatibility assurances, extra dependency), however it is worth considering making the implementation swappable.

Thanks @rpkilby , how do you suggest to do that?
