dtostrf() roounds upp (like sprintf("%f...)).
See https://github.com/lightaprs/LightAPRS-W-1.0/issues/7
Plus a feature for APRS higher precision position, see http://www.aprs.org/aprs12/datum.txt
Therefore I moved updatePosition() to updateTelemetry(), where decision is made if higher resolution is desired
(here heigth < 10000ft), i.e. for sending the exact landing position.
