About extrinsic_R #368

Hi,Thank you very much for making this excellent work available. However, I encountered some issues while using it. when i set extrinsic_R as Identity matrix,fast-lio2 can get a good result 。however,when i rotate 180° along the z-axis,The results are also good,do you know this phenomenon? I hope you can provide some guidance. former_extrinsic_R: [ 1, 0, 0, 0, 1, 0, 0, 0, 1] latter_extrinsic_R: [ -1, 0, 0, 0, -1, 0, 0, 0, 1] Result: Result
