Update on OpenLane-V2 Metric

[sephyli]

We would like to extend our gratitude to the authors of a recent arxiv paper TopoMLP, for highlighting an issue in the existing OpenLane-V2 metric. We've updated the OpenLane-V2 devkit to address this concern, ensuring more reliable and consistent measurements.

We have fixed the loophole in the new version of OpenLane-V2 devkit.

• v1.1.0: This is a Long-Term Support (LTS) version focused solely on OpenLane Topology (lane centerline).
• v2.1.0: The latest version for Driving Scene Topology (lane segment and map element bucket, and is also compatible with OpenLane Topology.

Please be aware that the updated metric might show inconsistencies with previous versions, particularly in the TOP_ll and TOP_lt metrics. We recommend reviewing the changes and updating your configurations accordingly to ensure the best results.
