New firmware version CN8E

As many ship installations gets new GPS/Glonass/Galileo receivers, many with enhanced position inaccuracy (= added decimal places), it has been a problem that NMEA messages sometimes gets longer than strictly allowed.

Our firmware was deisgned to check for NMEA syntax errors and discard messages not fulfilling all requirements, but this problem tended to create so much problems so we agreed, in collaboration with our customers, to modify the firmware of the CN8E to allow for NMEA messages having a payload of 140 characters.

However, please note that this is a violation to NMEA 0183 and IEC 61162-1 syntax and may possibly cause message interpretation problems in other connected equipment.
