Replace Google's DNS with Cloudflare

[x775]

Given the nature of this project, opting for Cloudflare's privacy-first 1.1.1.1 (1.0.0.1) DNS [0] above Google's seems reasonable.

Additionally, per DNSPerf, 1.1.1.1, is significantly faster than Google's [1].

Wouldn't quad 9 DNS be more appropriate? 9.9.9.9 blocks cyberthreats and known malware. https://www.quad9.net/

A DNS that blocks websites isn't good in my opinion, and I can imagine such a DNS blocking Bitcoin nodes. 1.1.1.1 is the best option.

Cloudflare supports DNS over HTTPS and support for that could be added.
