updated release notes
fixed unit tests with expected responses from getSample / getSampleMeta
moved flashing of logging LED back to loggerTask to avoid user surprises of changed behavior
made telemetry more robust to deal with edge cases if cellular module is power cycled while transmitting stream. apparently SIM900 doesn't return ERROR messages when it is sent json data - it simply echos it back, where RCP attempts to proceess as a command from the server. If 10 'bad' messages are detected, it drops and re-connects
