Occasionally getting an error on CI

SnapshotTesting/UIImage.swift:24: Fatal error: Unexpectedly found nil while unwrapping an Optional value

This is referring to a line here: https://github.com/pointfreeco/swift-snapshot-testing/blob/main/Sources/SnapshotTesting/Snapshotting/UIImage.swift

Which has some force unwraps.

I'm not sure why this is happening — possibly not even related to this repo.

But instead of force unwrapping and leading to a fatal error, this could presumably be handled more gracefully instead.

Hello @simondelphia, I got the same error, please check if *.png files are ok, in my case my was corrupted.

Yes they are corrupted. The cause of my issue has nothing to do with this library, so I didn't get into the details. Just would be nice if the library failed more gracefully.

@simondelphia But do you know how you resolved this issue?
