Regex presets to block scripts

[over-engineer]

One potential feature to consider is to include presets for commonly used regular expressions (for Google Analytics, Google Tag Manager, Facebook Pixel, etc.)

We could also include presets formatted to match a domain (with or without www.), a subdomain, etc.

For example,

Main domain regex:
^(?:https?:)?\/\/(?:www\.)?website\.com

Subdomain regex:
^(?:https?:)?\/\/(?:www\.)?sub\.website\.com

Example:
^(?:https?:)?\/\/(?:www\.)?google-analytics\.com
