Failed to load image: Insufficient memory

[micahsnyder]

I found a PNG image that fails to load with image-png through image-rs with the error message: Failed to load image: Insufficient memory

That's a pretty large iTXT chunk of 1314946 bytes in there. The problem: the decoder is allocating a vector with chunk contents and it's not using the limit configured for the pixel matrix, but a separate one .

Here's the same issue with more info https://github.com/image-rs/image/issues/1788

its not just text chunks that can be so large. This image for example has a 2mb caBX (jpeg metadata in a png file) chunk before the image data starts. I will try to fix this in a PR but i'm not yet sure how to access the limits in the StreamingDecoder, any helping pointers would be very appreciated.
