Verify an ed25519 signature.

@param key the ed25519 key.

@param signature the base64-encoded signature to be checked.

@param the result error if there is a problem with the verification.

If the key was too small then the message will be "OLM.INVALID_BASE64".

If the signature was invalid then the message will be "OLM.BAD_MESSAGE_MAC".
