Implemented optional feature GPT based similarity

[AtharvaJadhav7]

Used OpenAI API to create GPT embeddings, saved these embeddings in database in jobs table, they are created when job entries are created in the database. creating of embeddings again and again during ETL process is avoided to save API calls cost, by calling them only if there is no entry present for that particular key, same way as jobs are skipped. Changed strcture of jobs table to accomodate embeddings column, we can avoid showing that in app by just modifying query, but kept it there now, until functionality is completely full proof. Added a way to ask users for resume from user in streamlit interface, save that resume text in database as form of text. can update those entries too, if wanted. Added a button to use selected resume to get GPT based embeddings. Separated Run and Query Database to update and view database whenever wanted. this might be more user friendly as, there are optional features, so one can just run pipeline and then query database, or opt for features and then query database.

Also need to delete existing all_jobs.db file to create new tables as there are changes in structure. In ther video, the first error displayed was just to ensure the file does not exit from before
