Looking up the MIME of a file fails on Linux about nsfwspy.net HOT 3 CLOSED

From a quick look, I think this exception is getting thrown by the HeyRed.Mime package we use to help identify what image format we are classifying. ML.NET doesn't support the increasingly popular .webp image format, so to support it in NsfwSpy we convert that to a .png:

var fileType = MimeGuesser.GuessFileType(imageData);
if (fileType.Extension == "webp")
{
    using (MagickImage image = new MagickImage(imageData))
    {
        imageData = image.ToByteArray(MagickFormat.Png);
    }
}

I've just tried using this on a fresh Ubuntu virtual machine and see the same error message as you so I've just created an issue on their GitHub page to ask for clarification on whether an extra dependency is needed for Linux installs:
hey-red/Mime#44

Will update you when I hear back.

This issue should now be resolved in NsfwSpy v3.4.3.

@Krutonium are you happy to test the issue is now resolved for you when using the new version please?
