Merge story tag generation into main.

[ShinyMyst]

Includes the following:

• json dict of tag weights
• File to work with tag weights
• Function to pick tags for a story beat
• Test functions to experiment with odds of each tag occurring
• Slight tweak to README with internal terminology we use.

Fixed the the linting issues that was holding this up previously. Didn't realize I had them initially.

All files being added "should" be unique and not overlapping something existing.
