Bug fixes

• Respect user's color choice (d011f5e)
• Exit code should be non-zero if any files had errors or were not formatted (00a1bd1)
• Change the input files as direct argument (cacfbdc)
  • BREAKING! ⚠️ : this change the previous argument, where language is
    the direct argument. Now it is the file input. I see this pattern is
    more common than the previous design.

• Remove the feature flag (5d36ac8)
• Migrate to clap derive API (65dad31)
