This release adds a new module address - see README - with a new Address class and type which can be used for creating and representing Ethereum addresses.

Example usage:

import { Address } from 'ethereumjs-util'

const pubKey = Buffer.from(
  '3a443d8381a6798a70c6ff9304bdc8cb0163c23211d11628fae52ef9e0dca11a001cf066d56a8156fc201cd5df8a36ef694eecd258903fca7086c1fae7441e1d',
  'hex',
)
const address = Address.fromPublicKey(pubKey)

In TypeScript the associated Address type can be used to more strictly enforce type checks (e.g. on the length of an address) on function parameters expecting an address input. So you can declare a function like the following: myAddressRelatedFunction(address: Address) to get more assurance that the address input is correct.
