Allow EIP-3770 chain-specific addresses

[germartinez]

Overview

We are pushing to implement EIP-3770 address references, which include a prefixed chain id before an address. We need to allow users to input addresses with a chain prefix.

Goals

• Accept/validate EIP-3770 address input.

Requirements

• Modify inputs/validation to allow EIP-3770 address formats.
• Validate networks against this map. (A service will likely be created for this but it is acceptable to do this client-side in the web app.)
• Validate that prefixed addresses match those of the current network.

How about adding a getChainIdFromEip3770Address(address: Eip3770Address): number function?
