+  Module Info - extracts and prints the full module information from UBX_MON_VER

+
+  Previously it was possible to create and send a custom packet
+  through the library but it would always appear to timeout as
+  some of the internal functions referred to the internal private
+  struct packetCfg.
+  The most recent version of the library allows sendCommand to
+  use a custom packet as if it were packetCfg and so:
+  - sendCommand will return a sfe_ublox_status_e enum as if
+    it had been called from within the library
+  - the custom packet will be updated with data returned by the module
+    (previously this was not possible from outside the library)
+
+  Feel like supporting open source hardware?
