Adds safety goggles, grants team immunity to weather damage (Sandstorm and Hail)

[shayebeadling]

With how popular the trap moves are (mostly because of how they work with boss hp bars) I thought making the damaging weather moves better would be cool.

1. Adds a WeatherDamageImmunityModifier that prevents the team from taking damage from hazardous weather.
2. Hooks into the existing WeatherEffectPhase to check for the modifier and adjust accordingly.

TODO: Add them to the drop pool, I was thinking they would be a very low weight in the rogue tier pool, and the weight is boosted if the user has a damaging weather move.

Alright I've added them to the rogue pool with a normal weight of 1 (very low) But the weight is 10 if you have a relevant move or ability (Sandstorm, Hail, Sand Spit, Sand Stream)

TODO: I just found out that they also make the user immune to powder and spore moves, with the current team-wide implementation would that be too strong? My gut feeling is no, since there are only 8 of those moves and they aren't all that powerful, but I'd like to hear opinions.

Can you fix the conflicts and make these a held item instead of team-wide?
