Use Infura v3 API

[whymarrh]

This PR updates the project to use Infura's v3 API.

Tasks:

• Merge Use Infura API v3 eth-json-rpc-infura#32
• Update the eth-json-rpc-infura dependency here
• Pass a project ID to the NetworkController

Breaking change:

A project ID is now required for all instantiations of the NetworkController that are backed by Infura.

constcontroller=newNetworkController({infuraProjectId: 'foo',},{network: '1',provider: {type: 'mainnet'},});
