Add NAT information coming from firewall flows into Flowview

[TheWitness]

Is your feature request related to a problem? Please describe.

Now that we are storing the Templates, I see a lot of NAT information that we just ignore presently.

Describe the solution you'd like

Add this to the default tables, and upgrade legacy tables with these new columns.

Describe alternatives you've considered

Creating new table, which we won't.

Additional context

Need some example templates from a few vendors devices before diving in.

These columns look like targets. In MikroTik, there is a Template for IPv4 and another for IPv6.
