/**
* Common interface for all MAVLink Messages
* Packet Anatomy
* This is the anatomy of one packet. It is inspired by the CAN and SAE AS-4 standards.
*
* MAVLink 1 Packet Format
*
* Byte Index Content Value Explanation
* 0 Packet start sign v1.0: 0xFE Indicates the start of a new packet. (v0.9: 0x55; v1.0: 0xFE; v2.0 0xFD)
* 1 Payload length 0 - 255 Indicates length of the following payload.
* 2 Packet sequence 0 - 255 Each component counts up its send sequence. Allows to detect packet loss
* 3 System ID 1 - 255 ID of the SENDING system. Allows to differentiate different MAVs on the same network.
* 4 Component ID 0 - 255 ID of the SENDING component. Allows to differentiate different components of the same system, e.g. the IMU and the autopilot.
* 5 Message ID 0 - 255 ID of the message - the id defines what the payload means and how it should be correctly decoded.
* 6 to (n+6) Payload 0 - 255 Data of the message, depends on the message id.
* (n+7)to(n+8) Checksum (low byte, high byte) CRC16/MCRF4XX hash, excluding packet start sign, so bytes 1..(n+6) Note: The checksum also includes MAVLINK_CRC_EXTRA (Number computed from message fields. Protects the packet from decoding a different version of the same packet but with different variables).
*
* The checksum is the CRC16/MCRF4XX. Please see the MAVLink source code for a documented C-implementation of it. LINK TO CHECKSUM
* The minimum packet length is 8 bytes for acknowledgement packets without payload
* The maximum packet length is 263 bytes for full payload
*
*
* MAVLink 2 Packet Format
*
* Byte Index Content Value Explanation
* 0 Packet start sign v2.0: 0xFD Indicates the start of a new packet. (v0.9: 0x55; v1.0: 0xFE; v2.0 0xFD)
* 1 Payload length 0 - 255 Indicates length of the following payload.
* 2 Incompatible Flags 0 - 255 Flags that must be understood
* 3 Compatible Flags 0 - 255 Flags that can be ignored if not understood
* 4 Packet sequence 0 - 255 Each component counts up its send sequence. Allows to detect packet loss
* 5 System ID 1 - 255 ID of the SENDING system. Allows to differentiate different MAVs on the same network.
* 6 Component ID 0 - 255 ID of the SENDING component. Allows to differentiate different components of the same system, e.g. the IMU and the autopilot.
* 7 to 9 Message ID 0 - 16777216 ID of the message - the id defines what the payload means and how it should be correctly decoded.
* 10 Target System ID 1 - 255 (OPTIONAL) ID of the TARGET system. Only used for point-to-point mode
* 11 Target Component ID 0 - 255 (OPTIONAL) ID of the TARGET component. Only used for point-to-point mode
* 12 to (n+12) Payload 0 - 255 Data of the message, depends on the message id.
* (n+13)to(n+14) Checksum (low byte, high byte) CRC16/MCRF4XX hash, excluding packet start sign, so bytes 1..(n+6) Note: The checksum also includes MAVLINK_CRC_EXTRA (Number computed from message fields. Protects the packet from decoding a different version of the same packet but with different variables).
* (n+15)to(n+27) Signature (typeid, timestamp, sha256) (OPTIONAL) Signature which allows ensuring that the link is tamper-proof; 13 bytes containing typeid (1 byte), timestamp (6 bytes), and last 6 bytes of SHA256 hash
*
* The signature is a combination of a typeid, timestamp, and SHA256 hash.
* OPTIONAL fields mean that, if they are not used, they do not exist in the MAVLink frame at all. Typically target sysid and target compid are not used, and signature is only used if signing is set up between both ends.
*
* @see <a href="https://mavlink.io">mavlink.io</a> for more documentation on the MAVLink protocol
