Describe the feature

Waypoint map_marker packet appears to pack data in a different manner than used in the event parameters. Packet data seems to follow the table in the waypoints.lua from top to bottom with no offset or unused bits.

Need to:

1. Store data in core and db to align with packet
2. Add lookup to waypoints.lua global to convert to expected event params
3. Update map_marker packet to include waypoint unlocks (0x28~0x2E)
4. Create migration script to convert existing data to new saved format
