Added stat calculator

New class that will calculate stats like FIP and wOBA that BBR doesn’t
provide.
This is being used now to calculate FIP and wOBA in
PlayerSeasonStatsParser.
Fixed logging of unfound player name.

Previously, a player whose name doesn’t map from Rotowire to BBR would
be logged, but with the overwritten player_name that is None.  I’ve
saved off the player_name parameter as original_name and am logging
with that, so if player_name gets overwritten with None, we can still
see who the player is.
