address_gen.js does not generate internal addresses

[michaelbnewman]

address_gen.js generates external addresses only by default:

const AVAX_ACCOUNT_PATH = `m/44'/9000'/0'`;
let derivationPath = `${AVAX_ACCOUNT_PATH}/0/${i}`;

It would be nice to have option to also generate internal addresses (used when generating "spare change" in a transaction):

const AVAX_ACCOUNT_PATH = `m/44'/9000'/0'`;
let derivationPath = `${AVAX_ACCOUNT_PATH}/1/${i}`;

I added this feature in my PR in case this is still relevant
