Edge case with proto

[jacobzim-stl]

I did some fuzz testing with this library and found an edge case.

The JSON string "{\"__proto__\": 0}" is correctly parsed by the native JSON library into { "__proto__": 0 }, but in this library it is parsed into {}.

To solve, in the parseObj function update obj[key] = value; to
Object.defineProperty(obj, key, { value, writable: true, enumerable: true, configurable: true });

Thanks! I'm not very familiar with these JavaScript features, as I simply translated my Python implementation without a deep understanding of the JavaScript specifics. Would you mind creating a PR?

hey @jacobzim-stl ,
did you find any way to correctly parse it using partial-json?

i've also encountered with a similar issue now!

This can solve. I didn't update the code earlier because I didn't think this was a widely occurring problem, and using Object.defineProperty might introduce a slight overhead. @ashokasec, could you share the use case where you encountered this problem?
