Fix Unmarshal JSON of deck cards

Support for Cosmetics and March Update (#13)

Best of Three Support (#12)

This requires a little refactor. A match now contains a series of games,
and most fields are moved to the game. The algorithm for splitting
matches now looks for a new `MatchCompleted` end, and splits games by
sideboarding.

Better Handling of Missing Match Start (#11)

If the match start was missing, the pointer would return nil, which did
not use to be the case. This would cause a panic in those situations.
Check for the match being a nil pointer before dereferencing, and also
better handle the case in which it is nil.
