Add password wrap for V1-V3.

[TimothyMakkison]

Added support for V1-V3 password wrap for both local and secret. Bit of a pain because the test vectors/php implemetation was incorrect 😅

V2-V4 will require Argon2id, so I'll probably use the repository Konscious.Security.Cryptography implementation.

Looking at the source code ptk = XChaCha20(msg=edk, key=Ek, nonce=n) is implemented as sodium_crypto_stream_xchacha20_xor. Does NaClCore support this? I've found the php implementation but can't find the logic section, the rust equivalent looks a bit more promising.

Note that I rebased Lid, Pid and Sid onto this branch. Hopefully it won't cause problems.
