Build and Install Part of Ops in MMDetection3D

cd ${PROJECT_DIR}/third_party/bev_mmdet3d
python setup.py build develop

when building bev_mmdet3d, I got an error:
Exit status: error: Invalid distribution name or version syntax: bev-mmdet3d--0.1
then I check the setup.py, I found a syntax bug in the line
so I pull a request to solve that problem: #54
Would you help me to review and merge that request ?
