This PR adds four config options to configure whether and how to load
indutny/elliptic: use_indutny_elliptic, external_indutny_elliptic,
indutny_elliptic_path and indutny_elliptic_fetch_options.
Also:
- Use tweetnacl.js instead of indutny/elliptic for curve25519 key generation
- Don't initialize indutny's curve25519, improving performance when using that curve
- Verify NIST signatures using Web Crypto instead of indutny/elliptic when not streaming
- Move KeyPair.sign/verify to ecdsa.js
- Move KeyPair.derive to ecdh.js
- Move keyFromPrivate and keyFromPublic to a new indutnyKey.js file
This change implements Web Key Directory lookup using user's e-mail
address. The target host is the same as the e-mail's domain and the
local-part is hashed with SHA-1 and encoded using Z-Base32 encoding.
Implemented is basic flow of version 06 of OpenPGP Web Key Directory
draft [0].
It was necessary to update node-fetch package to allow returning array
buffers from HTTP responses.
If openpgpjs is used in the browser all keys retrieved from Web Key
Directory should have `Access-Control-Allow-Origin` header set to `*`
(including 404 Not found responses).

and make the high-level API accessible from an asynchronous proxy.
Entropy is seeded to worker on each generateKeyPair() call.
Allow serialization of packets and custom types for messaging API.
