/**
 * UDP-based implementation of the SegmentEmitter interface that sends trace
 * data to the X-Ray daemon using UDP. It has been mercilessly cannibalised from
 * {@link https://github.com/aws/aws-xray-sdk-node/blob/aws-xray-sdk-node%403.9.0/packages/core/lib/segment_emitter.js}
 *
 * By default, segments are sent to localhost:2000, but you can configure this
 * using the `AWS_XRAY_DAEMON_ADDRESS` environment variable
 *
 * The X-Ray daemon is a software application that listens for traffic on
 * UDP port 2000 and relays trace data to the X-Ray service. It is always running
 * on Lambda and is faster as it uses a UDP-based transport.
 *
 * For more details, see the
 * {@link https://docs.aws.amazon.com/xray/latest/devguide/xray-daemon.html AWS X-Ray Daemon documentation}.
