Data Addition (Valencia, Atlanta and RB Leibzig)

[Rijul1999]

Certain clubs such as Valencia, Atlanta and RB Leibzig have no data in our dataset, but they are present in the data that we will be predicting on. We need to scrape local games from https://datahub.io/collections/football in order to get the context for these clubs. We also need the data for every club even if we have examples of them in our database in order to generate the form vector for the clubs. The scrapers will be different for each league, so it will be better for different people to take up different leagues.
