Different prediction with tensorrt on refinedet model for the version v0.18.0 about deepdetect

[fantes]

Hi there, and thank you for the bug report

we were finally able to fix this, here : #1329

this PR updates TRT dependency (to TENSORRT 8.0.x), and unfortunately, this version has a bug https://forums.developer.nvidia.com/t/build-engine-error-when-use-pointnet-like-structure-and-tensorrt-8-0-1-6/183569/6
that affects ssd models.

Hopefully it will be fixed in net TRT update, and everything should then go as it should

Indeed we have a few tests (we need to add some more) but they are deactivated due to dependancies problems (compatibility between versions of tensorrt, tensorrt-oss, cudnn , ubuntu and correspnding docker images... )
Hopefully we will be able to integrate/activate them with TRT 8.x

Thanks a lot I'll try your fix!
I could be a good idea to add unit tests based on expected values for different models predictions to catch those, no?
