Allow collecting data from EUNE, NA, KR on top of EUW

- match_collector: query API and build collections for each platform
- match_collector: aggregate champion stats of each platform in one collection with platform annotations
- frontend: replace stats to count matches in platform-specific collections
- frontend: replace "EUW Challengers" with all supported platforms
- dev: adapted scripts to count match in platforms
