Output furuno proprietary attitude sentence (pitch and roll)
#1
The following flow takes the navigation.attitude SignalK delta provided by pypilot and converts it to the proprietary Furuno nmea0183 attitude sentence to get pitch and roll data into TimeZero (and possibly Furuno MFDs capable of reciving nmea0183).  Hope it comes in handy to someone.
