Prevent crashing for "Unsupported image type" error

[mari-rs]

Hi,

I hope this message finds all of you well. I have encountered an issue where the "Unsupported image type" error was being thrown in the setSource function of the canvas library. After investigating, I found out that this error was causing unexpected crashes in certain scenarios.

In my case these certain scenarios were pretty interesting. I have not been interacting directly with the library, randomly, my code crashed because of this error. My motivation to fix this error is a more robust code base, because in my case, my application should not crash in no matter what case.

To address this issue, I have added a try-catch block to the setSource function in the lib/image.js file. This should prevent unexpected crashes hopefully and ensures that the application can gracefully handle cases where the image type is not supported.

I have added the following code to address this issue.

function setSource (img, src, origSrc) {
 try {
   SetSource.call(img, src)
   img._originalSource = origSrc
 } catch (err) {
   img._originalSource = null
   throw err
 }
}

I will already say thank you for reviewing my pull requests! let me know if it's possible to apply these changes.

sincerely Rosie!
