chromakey hack

The idea here is similar to chromakey in obs, but I couldnt get the behaviour I wanted in obs so I made this hack instead.

Heres how it works:

• make a backround and a foreground image
• start the hack
• stand before your greenscreen, camera pointing at you
• the hack will show the background image, and you in silouhette form, Filled with the foreground image
• move about a bit
• close the hack
• now theres a video recording

I used Rust and OpenCV for this hack, so far it works great!
