Players and rosters work

[john-b-edwards]

In update-players.R:

• Swapping httr::GET() for httr::RETRY()
• Standardize representation of heights and weights

In update-rosters.R:

• Defining load_players() as a source of immutable biographical information
• Renaming some variables to fix some issues building rosters from data_exchange
• Rename some teams to be more consistent with their representation in load_rosters()
• Some reformatting

After approving these changes, I'll rebuild the players file, then all rosters files (and anything else this might touch... load_participation() too I think)?
