Put the "Auto" back into AutoOreDictConverter

Have an option (or make it the default) so that the mod automatically decides to which ore to convert to.
For example, on first world load, the mod looks trough the forge:ore list and uses the first entry of every type of ore as the target to convert ores to.
Then have a command to re-run the process, this way it is possible to recalculate in case a mod gets added/removed.

It ultimately doesn't matter what the ores get converted to, and this way there would be no configuration involved.

Start by tracing the mod's world-load handling and its ore conversion path, then inspect how the Forge ore list can be read. The work is done when an initial automatic target is selected for each ore type and a command can repeat that selection after mods change.
