[Feature Request] Allow for using multiple pallettes on the same output image

[MrDowntempo]

Option to use colors from multiple themes when catppuccinifing an image. For instance, if I have a desktop that is Latte during daytime and Mocha at night, i might want wallpapers that will be compatible with both without generating multiples. Also, selecting ALL themes togethor (latte, frape, mocha... etc...) would allow for a larger overall palette, which would help with certain images that don't catppuccify well.
