Description

Handle catching Strategy in Safari for RSE

SRE Safari zone unlike FR/LG is kinda straight forward.

How flee system works

There's a grade from 0 to 20 for the flee chance, which 0 is 0% and 20 equals 100%.
On the start of a fight the Pokémon flee chance is 3 (15%).
So we can NEVER avoid that flee chance of 15% at the end of the first turn, whatever we do.

Flee chance variation depending on the Pokéblock thrown :

Throwing a liked Pokeblock will get him to -2 (3 - 5). But if the value is negative the game will put the cursor to 1 (5% flee chance). And once it's at 1 it can NEVER go lower.

BUT, if we stat at 3 and we throw a neutral Pokéblock (not liked/disliked) then it can go to zero, and our Pokémon flee chance is now reduce to 0%.

Throwing a disliked Pokeblock doesn't have any effect so we don't want that.

Also some natures doesn't have some liked/disliked Pokeblock, so we can throw whatever we want, it will always be a neutral Pokeblock

At last, the "Go near" option increase the catch rate, but also increase the flee rate of the Pokémon, which is a very risky and mathematically not worth it strategy since we can reduce the flee rate to zero.

Implemented strategy

• Turn 1 : Throw a neutral Pokéblock, if there's none throw a liked (Reducing flee chance from 15% to 5%), if there's none just spam the balls
• Turn 2 and so : Spam balls

Changes

Updated nature JSON and class with Pokeblock like/dislike
Implemented the decide_turn_in_safari_zone in catch mode

As we talked previously on discord I think this is the best implementation for the cheats.yml version as it reads the Pokémon nature. So I could add this check to the PR and keep this for the cheat part
