games: widen foley pitch variance so takes are actually distinct

Browse Source 
vary was a per-step multiplier of ~0.05, capping the swing at a barely
audible +/-0.10. Redefine vary as the max deviation itself (chips +/-0.22,
cards +/-0.20) and spread it over seven pitch steps; give the single-take
shuffle a wobble too.
