Subject: [PATCH] Adds arctangent 2 component to circuits (#79892)

## About The Pull Request
Adds an arctangent 2 component (atan2)

## Why It's Good For The Game

It's made to convert offsets into angles, something thats pretty useful
in a coordinate based game
## Changelog
:cl:
add: Adds an arctangent2 component to circuitry!
