Event.player is None

When using the APMTracker plugin, it became clear to me that the events that the plugin parses the attribute player is None.

Code to reproduce:

class TestPlugin(object):

    name = 'TestPlugin'
            
    def handleCommandEvent(self, event, replay):
        print(event.player)
                
replay_file = '/home/rcortini/soft/sc2reader/test_replays/4.7.0.70154/1.SC2Replay'
replay = sc2reader.load_replay(
    replay_file,
    engine=sc2reader.engine.GameEngine(plugins=[TestPlugin()]))

which outputs a bunch of Nones.

By the way, this also means that the APMTracker plugin does not work, and that it is very difficult to write functional plugins.

Start with the GameEngine plugin path used by load_replay and follow handleCommandEvent for command events in the provided reproduction. Check how event.player is assigned while parsing the referenced replay and how APMTracker consumes it. Done means parsed command events expose the correct player and APMTracker and custom plugins no longer receive None.
