Fully Eurodex incorporation

[Apipilikas]

Eurovision official site serves a page that fetches information about the contest from Eurodex (eurovision dataset).

• Check if there is a way for developers to access this api.
• Otherwise, extend the eurovisionScrapper to scrape all the data from this site. Check next year if this changes significantly. We can either download and store the data in our repository or create a configuration file for scraping (?).
• Check misalignment with eurovision codes and eurotags. It is better to keep eurotags for our implementation but we have to create mappings.
