WKD Client

This library implements a client for the Web Key Directory (WKD) protocol
in order to lookup keys on designated servers.

Example: lookup public key using WKD

``js
import WKD from '@openpgp/wkd-client';
import { readKey } from 'openpgp';

(async () => {
const wkd = new WKD();
const publicKeyBytes = await wkd.lookup({
email: 'alice@example.com'
});
const publicKey = await readKey({
binaryKey: publicKeyBytes
});
})();
``
