Hangs when improper image content is encountered instead of dying

[Peter-Sparksuite]

Describe the bug

Tooling that produces the images shouldn't be producing invalid png images, but, it seems, pngjs is hypersensitive in some regard. When this happens, details about the error are displayed (stack trace & error message), but, the reg-cli tool hangs instead of completing.

/node_modules/pngjs/lib/parser.js:48
      this.error(new Error("Invalid file signature"));
                 ^

Node.js v18.20.1

Reproduced step

Steps to reproduce the behavior:

1. Images for comparison are created, with one or more having details that pnpjs appears to consider invalid
2. Run the reg-cli tool, specifying the new image folder path, the old image folder path, a path for the temp folder, --json {path to report.json} --report {path to report.html} --ignoreChange --matchingThreshold=0.05
3. Observe the error report shown above
4. Observe that the command never terminates

Expected behavior

The command should finish up with a non-zero return code and a message indicating the cause of the problem.

Actual behavior

The tool never completes. Output does show the error being encountered, but app hangs instead of finishes.
