Remove hard coded team object in __init__.py

[derek-adair]

A dicitonary of the various ways to refer to a team is stored in init.py

This seems odd and clunkyy. I think the team objects should be deduced so we dont have to update it if/when a team moves.

I am unsure of what side effects this has and it is probably not even worth doing xD

For example, JAX vs JAC for the jaguars. This is the only team formatted in this way where the abbreviation the nfl api returns is not the first slot in the array.

Ugh this is not possible without breaking update_schedule. This is used to look up historic data.
