Rotate camera image

[HughPH]

So here's the thing: My camera is hanging underneath my monitor. That means when I'm in a conference call, my eyes are looking above the camera instead of below it, which means they look more open. All the conference call software and recording software I use can flip & rotate as necessary. Unfortunately Howdy does not - and I couldn't find anything in the config for that either.

This could be implemented, but might be feature creep

feature creep?

Very good progress in #627
