Create players/teams specific queries for each sport

[tcash21]

I think it'd be great in subsequent versions to make the calls:

basketball_players(query=q_body)
basketball_teams(query=q_body)
football_teams(query=q_body)

and let the "stattle" or "perform" get used in endpoint specific calls.

Assume that we would want to specify league to help with things like CBB versus NBA.

Addressing these functions started in #14

I've been going through your hockey_players etc. w/ bball, so let me know if you want me to push, or if you're not done with them yet

I paused on those few helpers to get a sense of how you guys wanted to attack it. If you threw some together for bball, push something up and let's look at it!
