Add method to disable bulk tracking

[tsteur]

Adds a method disableBulkTracking.

This can be useful in some cases like below where maybe one method might want to send multiple requests but others only a single and you want to prevent that every method needs to know that bulk tracking is being used. Meaning for simplicity you only want to enable it for one method and then disable it again.

    private $tracker;

    public function trackTest(string $name, string $action)
    {
        $this->tracker->doTrackEvent('Foo', $action, $name, 1);
       // want to avoid needing to call doBulkTrack here and want to avoid bulk tracking enabled in constructor
    }

    public function trackFooBar(string $name, string $action)
    {
        $this->tracker->enableBulkTracking();
        $this->tracker->doTrackEvent('Foo', $action, $name, 1);
        $this->tracker->doTrackEvent('Bar', $action, $name, 1);
        $this->tracker->doTrackEvent('Baz', $action, $name, 1);
        $this->tracker->doBulkTrack();
        $this->tracker->disableBulkTracking();
    }
