Add X/Y wild encounters.

The following locations have multiple areas, which have been assigned
placeholder names (Unknown Area ###).

- Frost Cavern
- Glittering Cave
- Reflection Cave
- Terminus Cave
- Victory Road

No horde encounters because i'm not sure how we want to represent them.

No swarm encounters because they aren't in the normal encounter data.

Fixes #146.
