Create a palette preview image by using a simple config file

Big changes from v5 to v6!

This repository contains the v6 release candidate version of the code.
Check out the migration guide before upgrading.
v6 will be released to PyPi after final testing.

Usage:

1. pip install prev_gen
2. Open up the wiki to see how everything works
3. Create a file based on instructions (or just edit the python, yaml, json, or toml examples)

4. # in a python file
   palette = [...]
   from prev_gen import Previewer
   Previewer(palette)

   or use the cli tool prev_gen for conversions with no code

Example:

Inspired by the great Gruvbox theme, where even the preview is impressive
And so, below is the Gruvbox palette preview recreated with this app (click for selectable text)
