Add player slug to player box score and player season totals (75)

As 74 pointed out, player box scores and player season totals do not have a unique identifier.

The `data-append-csv` attribute on a player's name cell should be used - this value is the URI slug for a player's Basketball Reference Page.

Add `team_box_scores` client method that scrapes the `Team Total` rows from specific game page tables.

This method is called with specific `day`, `month`, and `year` parameters.

* Raise `InvalidSeason` error when season schedule response code `404`s (49 )
* Raise `InvalidSeason` error when player season totals response code `404`s (58)
* Parse player season total positions as list (60)
* Parse season total team enum as string (63)
* Raise `InvalidDate` error for non-`200` player box score responses (64)
* Fix Schedule Parser (66)

Fix schedule parsing for future games - specifically how game scores were being parsed (48 and 61 )

55 adds the `"F"`, `"G-F"`, `"F-C"`, `"G"` positions and hopefully resolves 54

Resolves 52 - Jimmy Butler's 2018 Phildelphia 76ers Season Totals include the position value `F-G`.

Normally, it's seemed that a player's season total position values for a particular team are limited to a single position.

Only when a player has played multiple positions for multiple teams over a given season are multiple positions indicated for that player, and only for the player's overall season total row.

Going forward, it might be better to parse that field as a list, if this trend continues.

However, this would be a breaking change and would need to be a major version upgrade.
