[Icon Requests from Feather] camera-lens

[karsa-mistmere]

As per #119 and feathericons/feather#221:

First is the original suggestion, I think that looks a bit too much like an orb as opposed to lens.
Personally not sure whether this icon is needed at all, all in all, I prefer the simplicity of the last one, albeit named focus instead of lens.

I understand your concerns. I agree. Let go with focus!
