User editable keys

Instead of adding different keys it would be better if they were user editable and we just save the state in localStorage or supabase. This will solve all other keyboard layouts as well.

I think localStorage is the way to go so we don't create unnecessary entries in supabase for users who play only once.

The controls should read localStorage > configControls or use default controls if none are present in localStorage
