text: Title: [LineZone] - flip in/out line crossing directions
  Body: ## Description
  
  Between `supervision-0.17.0` and `supervision-0.18.0`, releases in/out of the direction of the crossing were accidentally changed. Given that `LineZone` is one of the oldest features we have we do not want to make life difficult for users and want to restore the previous behavior. The change made in this [PR](https://github.com/roboflow/supervision/pull/735), most likely in this [line](https://github.com/roboflow/supervision/blob/0ccb0b85adee4202f5fe96834a374a057bbbd9da/supervision/detection/line_counter.py#L140), is responsible for the change in behavior.

  ### Minimal Reproducible Example
  
  You can easily confirm the crossing direction change between `supervision-0.17.0` and `supervision-0.18.0` releases using this [notebook](https://colab.research.google.com/github/roboflow-ai/notebooks/blob/main/notebooks/how-to-track-and-count-vehicles-with-yolov8-and-supervison.ipynb). Here are example results.

  ### Additional
  
  - Note: Please share a Google Colab with minimal code to test the new feature. We know it's additional work, but it will speed up the review process. The reviewer must test each change. Setting up a local environment to do this is time-consuming. Please ensure that Google Colab can be accessed without any issues (make it public). Thank you! 🙏🏻
