- Increased the effectiveness of animals for the Gathering of the Forsaken Souls ritual by a factor of 4.
- Added the framework for the Purification Altar.
Instead of creating a new file for each player with their UUID as the name, we create a single file and store it all in a List. That List gets converted to a UUID -> SoulNetwork map when read from the file.
MigrateNetworkDataHandler is used to migrate players from the old system to the new one. It reads both data files and sets the LP of the new network to the LP of the old network (if the old network is larger). Once conversion is done, we delete the old file so that it doesn't happen again and overwrite player progress.
This is an API breaking change due to an import change.
