Feature: Orchestration

[Exanlv]

The plan: Properly implement orchestration for sharding

Final usage should be something along these lines

$orchestrator = new Orchestrator(
  $totalShards: 16 // nullable to use Discords recommended amount
);

$orchestrator->on('allowStart', function (int $shardNum, int $totalShards) {
  // You spawn a seperate process for your shard
});
