Architecture
datagram.godefines basic constants like commands, on-device identifiers and datagram packets; as well as conversions of datagram payloads to golang typesbuild.godefines a datagram builder for assembling datagrams to sendparse.godefines a datagram parser which parses incoming bytes into datagramsconnection.goties builders and parsers into a bidirectional connection with the device, and defines convenience methods to synchronously query identifiers
