/**
* Roost's behavior should be defined as:
* The pokemon loses its flying type for a turn. If the pokemon was ungroundd solely due to being a flying type, it will be grounded until end of turn.
* 1. Pure Flying type pokemon -> become normal type until end of turn
* 2. Dual Flying/X type pokemon -> become type X until end of turn
* 3. Pokemon that use burn up into roost (ex. Moltres) -> become flying due to burn up, then typeless until end of turn after using roost
* 4. If a pokemon is afflicted with Forest's Curse or Trick or treat, dual type pokemon will become 3 type pokemon after the flying type is regained
* Pure flying types become (Grass or Ghost) and then back to flying/ (Grass or Ghost),
* and pokemon post Burn up become ()
* 5. If a pokemon is also ungrounded due to other reasons (such as levitate), it will stay ungrounded post roost, despite not being flying type.
* 6. Non flying types using roost (such as dunsparce) are already grounded, so this move will only heal and have no other effects.
