Since all games on a particular seed have the same starting player,
we should store this accordingly.
Note that this option is only used for old seeds (before 2020)
from the hanab.live database.
Regardless, we need to support this to be able to support these old
games.
Introduces a proper config file for db connection information
Also, connection now has to be explicitly initialized instead of this
being done on import: This is now done by the CLI function automatically
On hanab.live, some games have an invalid number of players
stored in the database, this leads to some games not being
able to be exported from the site.
We catch these cases and write occurrences to a local data file
We now only use relative imports for files in the same directory
Also, only modules are imported, never classes/functions etc
Furthermore, main methods in package files have been removed,
since they do not belong there
