v2.2.0 Windows x64 20/05/2024 Major

This release introduces a major new feature to Cactus Viewer:
Interactable thumbnail preview strip of current images in the folder (á la Picasa)

This feature is inspired by Google Picasa, which had something like this, a non-intrusive UI strip of thumbnails at the bottom that provided a nice overview of the images in the folder and allows you to jump between files visually. This feature is toggleable in the settings.

Other new additions:

• Added .ppm support through #42, thanks @hkva for the great work!

Note: The thumbnail strip feature is fairly new and involves using WIC to generate thumbnails of the files in the folder and upload them to the GPU, this is done on a separate thread and goes prograde and retrograde of the current file, I've ironed out the bugs I could find but you might discover something I didn't, please consider reporting any issues you can find by creating a GitHub issue here. In case the feature proves broken for you, there's a setting for it in the config menu to turn it off and in the json config in APPDATA under "settings_preview_thumbs".
