This message is used to read configuration items from the receiver. It returns the
configuration data for the specified items and layer.
A UBX-CFG-NAK message is returned in case one or more items are unknown to the
receiver or when the number of requested items is greater than 64. Otherwise a UBX-CFG-
ACK message is returned.
The configuration items are identified by their configuration key IDs.
