Done "megax"/"megay" choice options don't reflect in input log

[Mathy]

What type of bug are you reporting? Mechanics

What is the bug?
The "megax" and "megay" choice options are not reflected in a battle's input log. These are used by Let's Go formats and the Monkey's Paw mod.

(While not related to battle mechanics, I tagged this as Mechanics because input logging is part of the sim module.)

Are you able to replicate it? If so, how?

1. Start a battle that uses the "megax" and "megay" choices, such as Let's Go OU with Charizard
2. Use the choices in the battle
3. Use /exportinputlog
4. The input log will not have the mega choices at all
