rAV1ator CLI v0.0.3

Not a major update, but an update nonetheless: rAV1ator CLI 0.0.3

What's New:

• New encoder preset for aomenc: Animation preset has settings tuned for animated content.
• New Print option when prompted to start encoding; prints generated encoding command without running.
• Some dropdowns had dashes, removed those.
• Cleaned up some tooltips.
• Spinners for script generation separated from input file hashing for more consistent visual feedback.
• Revamped default aomenc parameters to make proper use of luma bias for "Default" & "HDR" presets.

That's all for now! rAV1ator CLI will update automatically on your system. Thanks for checking it out, and happy encoding!
