* If `message.data` has a valid snappy decompression, set `message-id` to the first 20 bytes of the `SHA256` hash of
the concatenation of the following data: `MESSAGE_DOMAIN_VALID_SNAPPY`, the length of the topic byte string (encoded as little-endian `uint64`),
the topic byte string, and the snappy decompressed message data:
i.e. `SHA256(MESSAGE_DOMAIN_VALID_SNAPPY + uint_to_bytes(uint64(len(message.topic))) + message.topic + snappy_decompress(message.data)[:20]`.
