	/**
	 * A message. The format of an N byte message is the following:
	 *
	 * If magic byte is 0
	 *
	 * 1. 1 byte "magic" identifier to allow format changes
	 *
	 * 2. 4 byte CRC32 of the payload
	 *
	 * 3. N - 5 byte payload
	 *
	 * If magic byte is 1
	 *
	 * 1. 1 byte "magic" identifier to allow format changes
	 *
	 * 2. 1 byte "attributes" identifier to allow annotations on the message independent of the version (e.g. compression enabled, type of codec used)
	 *
	 * 3. 4 byte CRC32 of the payload
	 *
	 * 4. N - 6 byte payload
	 *
