[Feature Request] Provide a "addressOrName" address resolver

[gregnazario]

🚀 Feature Request Description

Would like it easy to be able to have all apps simply deal with address or name in a standardized way, along with a display in a standardized way:

function resolveNameOrAddress({nameOrAddress: AccountAddressInput}): AccountAddress {
  // Regex `.apt`
  if (... .apt) {
    // resolve address
  } else if (accountAddress hex) {
    // load address
  } else {
    // error out
  }
}
