Convert ERR?_FLD_CD from a8 to i1
Drop game_info and parse_game_info

The game and event data is parsed simultaneously, so there's no need to
have a separate function for just the game info. I moved some of the
comments from game_info to the relevant new locations.
One more position that should be i1 instead of a8
Make the event text length much longer

Found an event text that's 49 characters long, so the previous limit of
8 was a bit short. Rearrange the line spacing some as well. Originally
planned on allowing the event and pitch fields to vary per game, but
there was little space savings without compression and very little to
none with compression. The complexity isn't worth it and removed it.
