[noise] Using X25519 keypair obtained by Ed25519 conversion

[Nazar Mokrynskyi]

Hi folks,

I'm trying to get Noise working with keypair that was obtained by converting Ed25519 keypair into X25519 keypair using library https://github.com/dchest/ed2curve-js (claims to be compatible with libsodium as an example, based on TweetNaCl).

However, Noise results in MAC failure during first ReadMessage() by responder (Noise_NK_25519_ChaChaPoly_BLAKE2b).

Should it work this way or am I missing something?
