Fortune Teller Flags

Fortune Teller sets 2 flags when leaving:

0x80406F98 to 4 (bit 3)
Uses: Makes the Fortune Teller talk to you on scene load when returning
Other uses: Is reset when skipping a cutscene (Lanayru cleared), can maybe be used to make other NPCs talk to you from far away?

0x80406FAB to 1 (bit 1)
Uses: Locks savefile location, prevents Epona from spawning

Both are event flags that lasts globally until manually reset or via softreset (not saved in savefile)
Set via d_save::dSv_event_c::onEventBit

r3 = 0x80406f98 = temp event flag region which are not saved in the savefile
r4 = 0x4 for 0x80406F98 (no offset, adds 4/bit 3) | 0x1301 for 0x80406FAB (0x13 offset, adds 1/bit 1)

Origins:
0x80406F98: talkProc (after remove, before getEventId)
0x80406FAB: evtProc_8daNpcT_cfv (after evtChange, before dStage_changeScene)
