Updated Metadata Sharing during Snapping

Updated the process where CartoPac Touch is able to copy specific metadata attributes during the process of snapping records. This new functionality will copy GNSS metadata from the target feature to the snapped feature. With specific consideration given to determining if the metadata needs to be averaged with other vertex data. Note that no post-processing metadata is included, CartoPac will still post-process the snapped records regardless of whether or not they were snapped.

Copying the metadata of the target feature ensures that CartoPac is capturing relevant metadata regardless of the vertex collection method.

This change only applies to the CartoPac Touch application.
