Changes made:

• Processing the iso3166.csv file Since it is said that we need to create the script for downloading the datasets from unstats.un.org website, currently I am busy with fixing the whole codebase, for this case I am currently doing it the same way as the original author's did. (Going to update it as soon as I finish with the current codebase).
• Added scripts/config.py file for easy access to all the links and column_headers
• Added scripts/iso3166.py script for easy creation of iso3166.json file
• Updated the scripts/edgar.py using selenium for parsing the sec.gov website
  • The reason I am using the selenium because sec.gov's sitemap disallows parsing through bs4 or requests, in terms of API it only worls for certain pages which are not available for these paths: /submit-filings/filer-support-resources/edgar-state-country-codes, in terms of GITHUB_ACTIONS there might be problems opening browser in the no --headless mode which are needed for parsing because in --headless mode it doesn't work, solution is to use Xvfb for setting up the pipeline
  • Updated the scripts/unterm_names.py script
  • Updated the scripts/format_json.py script
