This adds a driver for the Sagetech ADSB transceiver. The ADSB wiki page is getting a little out of date so I plan to update that as well.
It would be nice if some people could test with uAvionix Ping products just to sanity check that there is no impact on them.
Code change impact on fmuv1:
delta: 3688 program bytes
Example: convert dec 12345 to 0x12345 or dec 1200 to octal 1200
I removed the new param and replaced it with a simple ::detect() call that checks for the already-required serial protocol setting. This means only 1 thing is needed to be set instead of 2 to enable this sensor. This is also an easy way-forward for Sagetech MX and uAvionix's GDL90/UDP drivers which are in the pipeline
