Add support for PNG/APNG metadata

Post by Euphoria »

Please forgive if this is considered a crosspost as this feature would be very useful in both Classic and MP versions.
As PNG pretty much the most used lossless image format these days, so is the importance and usage of PNG Metadata has grown.
Please add support for viewing, editing, and saving PNG Metadata.
Included is an example image containing metadata critical to the context of the image.
