Adds points to the output of `client.players_season_totals` (133).

Resolves 95

Adds `outcome` and `points` fields to the values returned by the `team_box_scores` method (132).

Updating version to `4.5.1` after a bad build was released to `PyPi` that prevented parsers from being imported correctly.

`4.5.1` is the same source code as `4.5.0` except that outdated source code that caused the bad build for `4.5.0` were removed.

Includes changes from 119 and 129

* 119 refactored the parsing logic by representing HTML entities as classes, and using those classes as the interface that the transformation logic depends on. This created a clear separation of concerns whereas previously, logic about the HTML entities was intermingled with the transformation logic to convert the HTML into Python data structures.

* 129 added the ability to fetch regular season box scores for a given player/season combination. This was ntsirakis' first contribution 👏 !

This bug fix, resolved by 111, updates the column index for the `game_score` value when parsing daily player box scores.

Basketball Reference added a plus/minus column _before_ the game score column, which caused the web scraper to return plus/minus values instead of the game score values.
