JAnim v2.0.0

What's Changed

[BREAKING CHANGES]

• Prioritized cli_config as the highest priority, meaning --config parameters in the CLI will override all other configurations

• Renamed Item.digest_styles -> Item.set, this is used to apply style to all descendants;
  the previous name will be removed in JAnim 2.3
