Set release assistance indication %XRAI

The Nordic-proprietary %XRAI command sets Release Assistance Indication (RAI).v1.0.xv1.1.xv1.2.xv1.3.x

It is designed for cases where an application sends one packet uplink and expects one response back from the network or server. This can occur also at the end of an application session negotiation, where the application knows that it is going to send the last packet, for example an ACK to a server.

Note: Do not use %RAI if %XRAI is used.
