Features
- Made round_type column in match_results data more realistic, with later rounds being labeled "Finals" instead of all rounds being labeled "Regular".
Breaking Changes
- Changed the following data sets to match data generated by the fitzRoy R package
- `betting_odds`
- Removed `round_number` column, and made `round` column `int` type.
- `players`
- Made `round` `str` type, with text labels for finals rounds.
- Fixed column names for away team quarterly score events (e.g. `aw1g` should be `aq1g`).
- Made `pd.DataFrame` the default return type for data methods, because it's the data structure that most Python data people are used to working with, as well as being easier to work with than a list of dictionaries.
