Add Hidden Grotto Encounter method, Location Areas, and Encounters. (#1507)

* Add hidden-grotto encounter method

* Add hidden grotto - Unova Route 2

* Add hidden grottoes for Unova Route 3

* Add all hidden-grotto locations and encounters

Rate has been scaled up so all pokemon in a single location-area add
up to ~100. The 20% chance for a pokemon to spawn in a hidden grotto
is instead acounted for in the rate field of
location_area_encounter_rates.csv

The following pokemon had decimals after scaling, so they have been
rounded:
Zangoose, Seviper (Route 7, Route 23): 37.5 -> 38
Kingler, Corsola (Route 18): 37.5 -> 38
Pinsir, Heracross (Lostlorn Forest) : 3.75 -> 4 / 1.25 -> 1
Breloom (Pinwheel Forest - Inner): 18.75 -> 19
Amoonguss (Pinwheel Forest - Inner): 56.25 -> 56

Data sourced from https://wiki.pokemonwiki.com/ but adjusted to match
Bulbapedia, with one exception:
Mienfoo levels are listed as 50-54 in bulbapedia. This seems to be a
mistaken entry as all other Pokemon share the same level range within
a hidden grotto. Adjusted to match other Route 22 grotto levels.
