Several fixes for lineup scraper.

- When retrieving yesterday’s lineups to get a head-start, we’re
ignoring pitchers.  They won’t be playing the following day so there’s
no need to get their data.
- Added a map of lineup data to each player’s entry in the lineups
collection instead of simply a True value.  This contains data about
who their team is, who the opposing pitcher is, and where they are in
the batting order.
- Fixed issues with escaped player ids.  We’re now sending the correct
value to BBR scraper so “Connection Refused” errors aren’t happening.
