Hash collision using the same quality level and incorrect quality for WebP (#1431)
* fix: webp quality level mismatch * fix: hash collision using the same image ops Using the same image operations, but for different formats, e.g. `.jpg` and `.webp`, produced the same hash. To differentiate between these, the image extension is added to the hash.
