Feature: Generate subcommand, generate schemes from images!

Breaking changes:

• Printing colors with info command is now the default behaviour. Use -r or --raw to print just the codes.

Features:

• Added the generate subcommand!
  • You can generate nice schemes based on an image, choosing whether you want a dark or light scheme
  • Example usage: flavours generate dark /path/to/nice/wallpaper.png && flavours apply generated
  • For best results, i recommend making a simple script to grap your current wallpaper path, and run that whenever you update your wallpaper

Internal changes:

• Encapsulated both scheme and config
• Changed module hierarchy, now the operations are a submodule
