Please add Copyseeker as search engine

Is your feature request related to a problem? Please describe.
Except for TinEye and rarely Bing or Yandex, essentially all reverse image search engines have become garbage (IMO).

Describe the solution you'd like
I would like Copyseeker to be implemented into this extension, as I believe it to be the best engine currently.

Additional context
For some time now Google has killed their reverse image search and turned it into Google Lens, which I personally detest. It doesn't give me exact matches anymore and more often than not wants to sell me something. On top of that almost no reverse search engine offers resolution support anymore, which is something I used to love about Google's implementation (made finding larger version of an image I had a lot easier).

Chrome has a Copyseeker extension, but Firefox does not. Thus users need to manually download the image/copy the image URL and insert it into their website. I imaging this could be done easier through this extension.
