Assert failed when using type: BINARY for online_image

### The problem

I am attempting to use online_image with my [Adafruit Magtag](https://www.adafruit.com/magtag).
I have successfully displayed the image once but all attempts now results in an error.

If I use any other type (i.e. GRAYSCALE), I do not get the errors, but this image is not displayed properly.

I included a image component to show that the Magtag is capable of displaying the correct image.
I've tried a number of image hosting locations, to check if that's the problem.
