Batch event needed for all counters placed from a single effect

Currently when counters are added there is an event fired for each counter placed and one for all counters on a single card. At least two cards however, care about one or more counters being placed on one or more type of cards. [[Cloaked Cadet]] and [[Invisible Woman, Sue Storm]] need a `COUNTERS_ADDED_BATCH` to restrict their effects from triggering additional times. Cadet having a trigger limit restriction technically works to create proper behavior, but Invisible Woman would trigger for each hero having counters placed on it with the current `COUNTERS_ADDED` event.

Requirements:
- Create `COUNTERS_ADDED_BATCH` event
- Create Batch event class for counters added
- Create `addSimultaneousCountersAdded` method to `GameState`
