Cropping extracted PNG frames is now optional.

Some users do not want to automatically crop PNG sequences, added cropping as a checkbox toggle for these users. This is mostly related to the fact some people may want to remake spritesheets but more optimized or have an easier time lining up all animations into a single animated image for showcase purposes.

This cropping option only affects PNG sequences, it won't affect "single frame animations" as it's useless on them anyways.
It also doesn't affect GIFs/WebPs as they should be cropped automatically at all times.
