Migrate to Manifest V3

[dominik-korsa]

• Updated manifest.json to V3
• Fixed use of moved browser.extension.getURL function
• Replaced webRequest usage with declarativeNetRequest

These changes are enough to support Firefox, for Chrome support the background script must be converted to a service worker

Oh, nice, thanks for this! I've started some work at https://github.com/m4tx/satori-enhancements/tree/oof-manifest-v3 as well (fortunately, as far as I can see, we've done pretty much non-overlapping stuff, so we should be able to easily merge this together).

I should have some time this week to complete this, unless you want to do it, in which case — just let me know and go ahead ;)

It seems like most of the stuff is done now on the oof-manifest-v3 branch (incorporating your changes as well), i.e. the extension seems to be working just fine on Chromium. The remaining stuff is refactoring so we don't duplicate code between Chromium and Firefox (as we do now on said branch) and making sure it works 100%. I should be done with it by the end of today.

Incorporated into #46, thanks for the contribution!

I'll issue a release soon — maybe I'll even try to send it to Firefox Add-ons again (it has been removed some time ago with "Due to the limited/non-public audience of this add-on, this add-on is not suitable for being listed").

The 2.0 version is now available for Firefox on the Release page: https://github.com/m4tx/satori-enhancements/releases/tag/v2.0. It should be available in the Chrome Web Store soon as well, after it passes the review.

I've sent a request to the Firefox Add-ons reviewers about making it public again - we'll see what happens.
