v1.0.6

This PR:

• Adds a full set of helper methods for u-blox UBX message data extraction
  • See the updated UBLOX_Test.ino example for details. Increase BUFFER_Length to 100 bytes to view the NAV-PVT data
• Adds new helper methods to extract the UBX Class, ID and payloadLength
• Adds sempAbortNmeaOnNonPrintable and sempAbortHashOnNonPrintable
  • Allows much faster recovery if the SEMP gets stuck in either NMEA or Unicore Hash, waiting for an Asterix
• Adds verbose debugging
  • With verbose debugging enabled, debug messages are generated when the UBX / RTCM / SBF / SPARTN / Unicore Binary message length is known. Allows erroneous message lengths to be trapped much more easily
