Respect Global Privacy Control header

[fredster33]

Global Privacy Control is a new header (Sec-GPC: 1) that aims to replace Do Not Track. It's currently supported in Firefox and Brave, as well as a few extensions :)

Looks like it's not yet on the standards track. From the Mozilla website:

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

My browser (Brave) does support this, and was announced in 2020: https://brave.com/web-standards-at-brave/4-global-privacy-control/

#77 implements this.

It skips the .well-known/gpc.json file, but that could be easily added in the future if it became a MUST.
