replace org.json.JSONObject vs GSON/Jackson/Moshi

[sandys]

we use JSONObject in multiple places. If we can reduce amount of code using GSON/Jackson/Moshi - we should do that.

Performance is not the top criteria here.

Some benchmarks you can have a look at.
I think Jackson does look better according to the above link.
Could work on this, if you want.

@kamathis4 that sounds good! this should be a relatively straight forward...but very impactful project if u do it.

P.S. dont forget to add testcases

[sandys]

@kamathis4 one of the reason we are preferring GSON/Moshi is because of #220

there is a very interesting path there to take!

[adi-kmt]

So you suggest moshi since it's easily interoperable with android?

@kamathis4 would love to hear your thoughts and evaluation!
