SKBitmap.ByteCount should support images >2GB

[ziriax]

The following code is problematic for large images, it throwns an overflow exception

 /// <summary>Returns the byte size of the pixels, based on the <see cref="P:SkiaSharp.SKBitmap.Height" /> and <see cref="P:SkiaSharp.SKBitmap.RowBytes" />.</summary>
    /// <value>The byte size of the pixels.</value>
    /// <remarks>Note: this truncates the result to 32-bits.</remarks>
    public int ByteCount => (int) SkiaApi.sk_bitmap_get_byte_count(this.Handle);

I suggest to convert this to a long or ulong?

We can't convert, but we can add link here:

Maybe not the same code, but also to avoid the crash for now you can use bitmap.Info.ByteSize64 and see if that fixes it?
