Adding a segmentation model to jetmulticam.models

[eliabruni]

Hello @tomek-l

This looks great, thanks for making it available!

I just managed to deploy a deeplabv3plus from mmsegmentation with TensorRT engine to a Jetson Xavier, which reaches up to 50FPS.

Next, I would like to run my segmentation pipeline on 6 e-CAM25_CUXVR CSI-2 cameras. What would be the steps to add my segmentation engine to jetmulticam.models? Could you help out with that? With some guidance, I could try to do it myself and make a PR :))

Thanks!
