msg ROS2 compatibility, microdds_client improvements (timesync, reduced code size, added topics, etc), fastrtps purge
- update all msgs to be directly compatible with ROS2
 - microdds_client improvements
   - timesync
   - reduced code size
   - add to most default builds if we can afford it
   - lots of other little changes
 - purge fastrtps (I tried to save this multiple times, but kept hitting roadblocks)

# Fused global position in WGS84.
# This struct contains global position estimation. It is not the raw GPS
# measurement (@see vehicle_gps_position). This topic is usually published by the position
# estimator, which will take more sources of information into account than just GPS,
# e.g. control inputs of the vehicle in a Kalman-filter implementation.
#
uint64 timestamp # time since system start (microseconds)
uint64 timestamp_sample # the timestamp of the raw data (microseconds)
float64 lat # Latitude, (degrees)
float64 lon # Longitude, (degrees)
float32 alt # Altitude AMSL, (meters)
float32 alt_ellipsoid # Altitude above ellipsoid, (meters)
float32 delta_alt # Reset delta for altitude
uint8 lat_lon_reset_counter # Counter for reset events on horizontal position coordinates
uint8 alt_reset_counter # Counter for reset events on altitude
float32 eph # Standard deviation of horizontal position error, (metres)
float32 epv # Standard deviation of vertical position error, (metres)
