feat(tailwind colors): add exact colors, style, and color name

[nicolas-cherel]

• now supports styles, if a style is used for a figma node, its styles take precedence on node fills. (probably need factorization for other frameworks) • add a setting to only allow named color for exact matches with tailwind • use figma name, either alias or style for colors. Those colors need to be added to tailwind configuration.

Hey @nicolas-cherel - you might want to look at two recently-merged PRs which will affect your code:

• #109
• #110 (also modifies how colors are picked)
