Implement Scraper for the New MTGO Site

[Badaro]

After the migration to Daybreak MTGO has a new website for decklists: URL: https://www.mtgo.com/en/mtgo/decklists

The format does not match the one used by magic.wizards.com, so I'll need to implement a new scraper.

Tasklist:

• [x] Write a scraper for the tournament list
• [x] Write tests for the tournament list
• [x] Write a scraper for the Leagues page
• [x] Write tests for the Leagues page
• [x] Update scraper for the Prelims page
• [x] Update tests for the Prelims page
• [x] Update scraper for the Challenges page
• [x] Update tests for the Challenges page
• [x] Remove magic.wizards.com scraper and tests
• [x] Scrape some data and run the validator, apply normalization fixes
• [x] Ingest all data from mtgo.com
• [x] Move magic.wizards.com folder to archive

Checklist for known website issues so I can track if any are fixed and/or work around them.

Major issues (require a fix on their site or a workaround in code):

• [x] It's ignoring Top 8 and ordering only based on the swiss, example here (Workaround implemented)
• [x] Missing cards in some lists (see HamburgerJung here, which is missing Fire // Ice unless you change sorting) (Rendering bug on the website, already fixed)
• [x] Duplicate decklists in some pages (see leandru here, which shows up twice). And duplicate lists are NOT identical. (Workaround implemented, required different fixes for League and Prelim/Challenge pages)
• [x] Card names broken in some pages (search for "Vial" here, will need to review data with Validator later and implement fixes) (Workaround implemented)
• [x] JSON data can contain the same card multiple times (likely considering printings intead of cards). (Rendering in the website handles this, but a workaround was also required for the scraper)

Minor issues (don't need fixing, but relevant to document):

• 5-0s contain different decks from the old site, compare this one with the new version
• The date in the list page is the event date, unlike the old website where it was the post date (usually a day after)
• Uses a different format for split cards ("Fire/Ice" vs "Fire // Ice"), this should already be handled by the current normalizer but it's relevant to test. (confirmed during implementation that the normalizer handles this correctly)
• Anchors have the same problem as the old website where if a player shows up twice in the same page you can only do a direct link to the first entry.

Deck page:

• Will require HTML scraping. Seems fairly clean/easy to parse though.

Event page:

• Looks like all the relevant data is in a JSON blob, look for "window.MTGO.decklists.data". Sample JSON: https://pastebin.com/raw/U8iysY39

Basic implementation done and online, for now only downloading new events.

Will wait to see if there will be further fixes to mtgo.com before moving on to the larger scraping of the event history.
