/**
Verify an ed25519 signature.
@param signature the base64-encoded signature to be checked.
@param key the ed25519 key.
@param message the message which was signed.
@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".
@return YES if valid.
