Add auto-populated GNSS metadata fields for lines and polygons.
Currently there are 22 GNSS metadata fields that can be added to the feature services used in Field Maps. These fields provide critical information without the need for the field data person to enter information manually. Some of the GNSS metadata fields currently available would be very easy to add, like "Receiver Name" (ESRIGNSS_RECEIVER). Other fields would require calculating averages or ranges, like "Average PDOP" or "Maximum PDOP" instead of "PDOP" (ESRIGNSS_PDOP).
