Add default record file name
When recording a stream, this adds a default name to the pcap file in the record dialog.
The default name is based on the first LiDAR interpreter found, by using the interpreter->GetDefaultRecordFileName()
method.
If the LIDAR interpreter that is being used does not override this method, the default behavior is YYYY-MM-DD-hh-mm-ss.pcap.
This also opens the save record file dialog at the same location as the last saved recorded file.
