Wake word and animation sprites

[chadbailey59]

Extracted from my work on the Golden Kitty project.

This PR adds:

• ImageListQueueFrame to enable basic list-powered sprite animation
• 10-wake-word.py to examples, which includes:
  • A TranscriptFilter to get rid of bot transcripts
  • A NameCheckFilter to filter transcripts to only sentences that mention a specific name
  • A 'talking' sprite animation, using ImageSyncAggregator

This branch does have the daily-bot-manager.py and auth.py files from llm-bots, as well as a Dockerfile that builds this toolkit to run on the Santa Cat AWS infrastructure. I'm not sure if we want to bring that into this repo officially or not.

A few minor comments, plus what I said in-thread about moving Dockerfile, auth.py and daily-bot-manager to the samples directory, but looks great! Thanks for doing this.
