YSCE Build Number
ysce-rwr-testing (JOBBIN Build)

System Specifications
Operating System: Windows 10
CPU: AMD Ryzen 5 3600
GPU: NVIDIA GTX 3060 12GB
RAM: 32GB DDR4

Describe the bug
Aircraft on the RWR that are not facing towards the player shouldn't show up on the radar.

To Reproduce
Steps to reproduce the behavior:

1. Enter any air combat mode.
2. Fly behind an aircraft
3. Notice their RWR track is present on the RWR HUD indicator.

Expected behavior
RWR Tracks for aircraft that are not 'illuminating' the aircraft (within the weapons lock FOV) shouldn't be present.

Additional context
This isn't that big of a deal right now since we implemented the RWR as a basic implementation for use later, but it helps to know this is an issue that needs to be sorted before we do anything more advanced.
