User settings to open external links using privacy-centric alternatives [Feature Request][Enhancement]

[lima46zulu]

Replace links to Youtube, Twitter, Reddit by private alternatives.

It would be great if links to mainstreams sites could be replaced by privacy-centric alternatives. It would probably be a user setting, similar to what Nitter has on this page. https://nitter.net/settings?referer=%2F

For example, links to twitter could be replaced by links to Nitter:

Links to Youtube could be replaced by links to Piped:
