Filtering talkers on NMEA2000 networks

On some (poorly configured) NMEA2000 networks, you can have more than one talker for depth, system time, and position. These are often not consistent, or reliable. Therefore, when the file is converted, you’re going to get an inconsistent sequence of data which will cause problems when processing to GeoJSON (specifically in interpolation).

Therefore, it would be useful to add the ability to tell the WIBL logger to ignore particular talkers on the network as part of the NVM configuration.
