feature: Add network interface filtering (#381)

Adds a new option in the config file to filter out network interfaces.  Also add the option to filter by whole words.

Interface follows that of the existing ones:

```toml
[net_filter]
is_list_ignored = false
list = ["virbr0.*"]
regex = true
case_sensitive = false
whole_word = false
```
