no decode delegate for this image format `TMP' @ error/constitute.c/ReadImage/746 after update to 14.7.0

Hey,

After upgrading Magick.NET-Q16-AnyCPU from 14.5.0 to 14.7.0 due to the security vulnerability, I'm running into an issue with my current image conversion implementation.

My implementation looks like this (general idea, so you can get the picture):

// First, the image is uploaded to a temporary directory with the .tmp extension.

UploadImage(IFormFile image) {
	string tempName = Guid.NewGuid().ToString();  
	string imagePath = Path.GetTempPath() + tempName + ".tmp";

	await using (var fs = new FileStream(imagePath, FileMode.Create)) {  
    await file.OpenReadStream().CopyToAsync(fs);  
	}

	return imagePath;
}

// Then, Magick.NET is used to resize the image.

ResizeImage(string tempImgPath) {
	using (var image = new MagickImage(tempImgPath)) {
		//Process image
	}
}

The issue now, is that I'm getting the following error:

no decode delegate for this image format `TMP' @ error/constitute.c/ReadImage/746

Downgrading the package to 14.5.0 fixes the issue, but the security vulnerability is present. I assume this has to do with the security settings for ImageMagick, but I am unsure of the best way to change those settings. Any help in this matter would be greatly appreciated. Thank you

What is the image you are using? How can I reproduce your issue?
