AdServers for Little Snitch 4

A very ~~hacky~~basic script to convert Peter Lowe's AdServers blocklist to the JSON-based Little Snitch 4 .lsrules format, suitable for use as a Rule group subscription.

It is worth noting that @pgl provides a littlesnitch-rule-group-subscriptions format, but this script uses the more compact denied-remote-hosts array format introduced in Little Snitch 4.1

This script requires internet access at least once, to curl the host blocklist, and emits JSON on stdout.

Subscribe rules are embeddable using the x-littlesnitch: URL scheme.
