feat: Add publish package

[rpechuk]

This PR contains and MVP for the new Publish CLI tool that will be used to transform YAML/JSON specs into shippable visualizations.

Current Changes:

• Added mosaic-publish CLI tool for compiling and optimizing specs, handling data export, interactivity, and optimizations.

TODOs:

• Add more user control over optimization params/streamline current user control (selective dataset inclusion, DuckDB export settings, granular optimization flags, etc.).
• Refactor duplicated logic between MosaicClient and new base classes. Namely combine both base classes into one base class that discribes any activatable client. (See feat: consolidated activatable logic to core #683)
  • Open Question: Where should this be created since these span multiple packages
• Expand README and add tests for CLI and utilities
• Add further optimization and improve upon current optimizations:
  • Namely work on better pre-rendering + hydration
  • Automatic Tiling implementation
  • Cache hydration
  • Smart spec re-writing
  • etc.

Open Questions:

• How should we handle interactive pre-rendered visualizations before data is loaded?
• Are there any better/other output formats we should support?
• Is the current way of handling dependencies correct (w/o relative reference to package and instead using npm version)?
