Create functionality to extract LOINC Delta updates to generate additional embeddings

[BradySkylight]

Description

This PR includes changes to make it possible to perform updates against, at least LOINC for now, various medical terminology value-sets utilized by TTC. Below is a list of the changes you will see:

• Another refactor that moves the common functionality for All value-sets (general.py) as well as specific functionality for each of the different value-sets/ontologies into their own util python script.
• The old valuset_sync script has been renamed to 'extraction' and leverages the utils functionality to perform a FULL extraction and saves the various files
• The readme has been updated to indicate naming changes and location changes for various files/functionality
• The embedding notebook was also changed to reflect the new order of all LOINC data pulled from LOINC extract so it will work correctly if ever used again.
  • NOTE: There are some formatting changes in this file for some reason and I'm not sure why - ignore these unless you notice an issue
• Added a maintenance.py to handle maintaining the valueset extracts and embeddings for all valuesets - though only LOINC has been implemented so far for loinc lab names, as this is the only valueset loaded in our model at this point.

Closes #452

Additional Notes

I haven't added in tests, but have tested along the way and have some print statements included for now just to see the end result. The output will be passed to the next step - create the embeddings - which will then be stored as files somewhere and then uploaded into OpenSearch.
