Replace most of libsodium with Noble cryptography

[o-az]

cosmjs/packages/crypto/src/index.ts

Lines 5 to 13 in 5c1ec56

	export {
	Argon2id,
	Argon2idOptions,
	Ed25519,
	Ed25519Keypair,
	isArgon2idOptions,
	xchacha20NonceLength,
	Xchacha20poly1305Ietf,
	} from "./libsodium";

Ed25519 -> https://github.com/paulmillr/noble-ed25519
Argon2id -> https://github.com/paulmillr/noble-hashes#argon2

You already use libraries from the same author so I assume you're familiar with the work quality.

I'm suggesting this because libsodium is massive which makes it extremely hard to justify cosmjs unless the project is very large.
