Chrome MV3 will break Webrequest

[eslerm]

When Google Chrome switches to Manifest V3, extensions will not be able to use Webrequest. Potentially MV3 will break other parts of Neat-URL.

Neat-URL may need to:

• Be overhauled to meet MV3
• Drop Chrome Support
• Fork between a MV3 and non-MV3 extension

This will impact how #288 is dealt with.

I was aware of this, but thanks for bringing it to my attention again.
