Added Smoothing Feature to FOV Changes

[ELevin125]

Changes Made:

• Updated the PIL Image scaling code to use the LANCZOS instead of ANTIALIAS, since it's outdated and throws errors.
• Implemented a smooth transition feature for FOV changes, allowing the FOV to smoothly transition from the current FOV to the target FOV instead of snapping directly to it.
• Added UI elements to control the smooth transition behavior. It can be toggled on and off, and the duration and steps can be changed.

Sorry for answering so late! I am currently having my final exams. As soon as I get some more time on my hands, I'll look into merging your code and making a new release.

So far, your addition looks great! Thank you that you undertook the effort of adding a feature to this horrible codebase!

I tried this out, it works fine. My only issue is that the linear transition feels unnatural. Perhaps a cubic bezier or exponential curve instead?

Ok, I've done a bit more testing. Here are my observations:

• When you set the duration to be high (e.g. 1 second) there is input delay at the start. The use of time.sleep also should be removed seeing that the Thread class is used elsewhere.
• Stopping the app when it is transitioning to a new FOV causes a crash.
