Ruby is the best. ❤️

Ruby doesn't care about whitespace.

This PR duplicates some of the Python functionality with Ruby.

This PR is greatly aided by using Synthea bundles generated with this Synthea branch, because it adds labs and diagnostic reports to the simple templated notes: synthetichealth/synthea#1589

This PR requires manual changes to ruby/llm.rb to function, notably replacing the DEFAULT_MODEL (string) and the MODELS (hash) with model endpoints that are accessible to the user.

For example:

    DEFAULT_MODEL = 'my_model'
    MODELS = {
      'my_model' => ['https://my_model.example.org', 'my_model/model-5-99B-Super'],
    }
