graphics/walllust: update to 3.0.0nb2

New major version, changes from the beta pre-release:

 - update deps, man pages, completions, readme, v3.md
 - output of image is now the basename
 - wallust doesn't require a config file, because of this, the default config \ 
file has been simplify to what most people would 'expect', avoiding advance \ 
configuration.
 - fix a cache bug (bdd133771d)
 - make some common cli flags globals. (aa7c7af753)
 - new -N/--no-config global flag
 - template:
    * add colors array (906ce4b1f8)
    * HEXA representation of colors (e48c376984) #41
    * avoid UNC windows paths (53efe6ea92) #42
 - overall MASSIVE changes to the code => instead of implementing some \ 
functionality manualy, I'm using the palette crate which is very refined and \ 
displays much better results.

BREAKING:
 - rename generation to fallback_generator (a9548c24a8)
 - rename --config-path to --config-file (735bd3861b)
