Subject: [PATCH] Update AVFileType+Extensions.swift
MIME-Version: 1.0

when I'm using iOS13.5 simulator, everything works fine, however when I'm using iOS15 simulator, when I pick a video from photo library I got this error;

```
Could not calculate the thumbnail size.
Could not calculate the thumbnail size.
🖼 YPImagePicker. YPVideoFiltersVC.swift -> save() -> Export of the video failed. Reason: Optional(Error Domain=AVFoundationErrorDomain Code=-11838 "Operation Stopped" UserInfo={NSLocalizedFailureReason=The operation is not supported for this media., NSLocalizedDescription=Operation Stopped, NSUnderlyingError=0x6000015c81b0 {Error Domain=NSOSStatusErrorDomain Code=-16976 "(null)"}}) (line: 218)
```

with the configuration of:
```
config.video.fileType = .mp4
```

After analyzing your source code, I noticed that it returns "None" as the extension, I was suspected maybe this was the reason,I have fixed this function, everything works on iOS 15 simulator now.
