Support for BigNumber and BigInt

[michaelessiet]

Describe the feature

I'm requesting for BigNumber and BigInt data types to be supported because nowadays Javascript is used almost everywhere and anywhere it runs, whether that be on the server, client or others.

While using Javascript with cryptocurrency or web3 libraries I have noticed that it's almost impossible to develop anything production ready without using a BigNumber or BigInt data type. The same applies for data analytics, I came to the cross road of having to choose between python or javascript while building an analytics formatting and filtering script for the place I work. Long story short, I went with python since it supports numbers greater than 2^32 without an external package
