Add some pbr mode restrictions based on team sizes

[ghost]

The following are restricted, both for token matches and autogenerated matches:

• 1v1 secrecy and randomorder matches
• 1vX traitor matches (since traitor will always swap the 1st pokemon)
• fog, letdown, sketchy, and bulk-2.0+ cloned pokemon* where one team has >3 pokemon
• rainbow, boing, hitandrun, and bulk-1.5+ cloned pokemon* where one team has >4 pokemon

* bulk ratio is defined by:

def meets_base_stats_bulk_ratio(mon, ratio):
    basestats = mon['basestats']
    return (
        ((basestats['hp'] + basestats['def'] + basestats['spD']) / 3)
        /
        ((basestats['atk'] + basestats['spA']) / 2)
    ) >= ratio
