[Enhancement] ReferenceGenerator class in package_builder.py

1. Why?

   For better code organization, scalability and maintenance

2. What?

   • Class ReferenceGenerator is added in package_builder.py to create openbb/assets/reference.json file
   • Modified Platform Markdown Generator v2 to reflect changes from the reference.json for correct docs generation
   • Fixed docstrings for the quantitative, technical and econometrics functions
   • Added logic to check if all extensions are installed before generating the doc file

3. Impact

   • Impact : Moderate
   • Impact Score = 18
   • Not backwards compatible due to breaking changes from the refactored examples
   • New class with code to create a new file may impact performance
   • Maintenance needed between all the classes and methods to ensure they work cohesively

4. Testing Done

   • Auto-build and manual build triggered to check the change in files
   • Docs built and tested locally on npm server to ensure they are similar to the deployed docs

5. Reviewer Notes

   macOS/Linux systems will show Reference column in random order on the local npm server. This is fine as it does not affect the docs when they are deployed on the website.
