[Enhancement] Option to add host filter

[leogbar]

First of all, this is a great app.

Second, can be good include a option to add host filters, own filters o another's filters. Thanks for your work!

Thanks for your kind words.

Yes, this is planned but isn't likely to ship until September given other high priority items in the backlog. :)

@leogbar see also: blocklists bundled with the app are open to community inputs here: https://github.com/serverless-dns/blocklists.
