Use json-bingint to parse JSON body

[krithika369]

The Response.json() API does not have provision to handle BigInt.

This PR introduces an option parseBigInt that can be sent to the useApi hook, which, if set, would use the custom json-bigint library to parse the JSON body instead. This will result in a custom BigNumber object where the number is larger than MAX_SAFE_INTEGER.

Example:

Do we know the implications of using this library compared to response.json()? Is there any difference in performance between the two? I'm not super comfortable to switch to it as it's affecting pretty much every MLP component. Can we make support of it as an option in useApi hook (default to false)?

@romanwozniak thanks for the feedback. I agree with the concern and looking closely, I see a potential open issue in the library as well: sidorares/json-bigint#39

Added the parseBigInt option to keep it conditional.

Thanks, looks good to me!
