Bump web3 and reintegrate

After doing some research into web3 alternatives I couldn't find anything that has typescript support out of the box that fills the same use.

One possible thing to explore in the future is ethers.js, which is undergoing a rewrite in Typescript.

Also there are proper typings for Web3, but they are currently broken, so this may improve in the future.

The immediate work around is just to type the web3 object as any
