(G)FSK Get_PacketStatus() command
Get_PacketStatus(Status, RxStatus, RssiSync, RssiAvg) returns information
on the last received packet. Depending on the selected packet type in Set_PacketType()
sent prior to this function, the parameters for generic packets are interpreted as below.

LoRa Get_PacketStatus() command
Get_PacketStatus(Status, RssiPkt, SnrPkt, SignalRssiPkt) returns
information on the last received packet. Depending on the selected packet type in
Set_PacketType() sent prior to this function, the parameters for LoRa packets are
interpreted as below.
