[Bug] `readImage` crashes on malformed json

This one test image crashes due to malformed JSON but other viewers (like ImageJ) can open it (but maybe they're catching/continuing silently?)

[5mg_20x_k14_ki67_5.tif](https://github.com/user-attachments/files/30198764/5mg_20x_k14_ki67_5.tif)

The image is from the image.sc forums so I'm assuming not sensitive. https://forum.image.sc/t/errors-in-piximi/116413. It's a pretty recent thread but the microscope/software could just be old.

```
Uncaught (in promise) SyntaxError: Unterminated string in JSON at position 525 (line 30 column 30) (at index-CNKmEHeQ.js:3638:594)

I'm not able to reproduce with `readImageNode` but I am able to reproduce using the [official documentation's](https://insightsoftwareconsortium.github.io/ITK-Wasm/image-io/ts/docs/#/) "Live API Demo"

Start with the official ITK-Wasm image-io Live API Demo and the supplied 5mg_20x_k14_ki67_5.tif file, then compare the reported readImage failure with the readImageNode behavior. Trace the JSON parsing error in the image-reading path; done means the malformed file no longer crashes the demo and its handling is covered by an appropriate test or reproducible check.
