Add benchmarks using * and **

Benchmark results:

EventEmitterHeatUp x 9,677,767 ops/sec ±0.54% (100 runs sampled)
EventEmitter x 4,637,885 ops/sec ±0.32% (99 runs sampled)
EventEmitter2 x 8,132,665 ops/sec ±0.40% (96 runs sampled)
EventEmitter2 (wild) x 4,538,810 ops/sec ±7.98% (93 runs sampled)
EventEmitter2 (single-level wildcard) x 251,624 ops/sec ±0.41% (102 runs sampled)
EventEmitter2 (multi-level wildcard) x 187,027 ops/sec ±0.60% (99 runs sampled)

Fastest is EventEmitterHeatUp


Wildcard results as expected but why is EventEmitterHeatUp so quick? I get that every time.
