Fix install errors

[sam-writer]

Update requirements_gpu.txt and add nvidia-pyindex to GPU requirements, so nvidia-tensorrt install works. Also add the wheel requirement to setup.cfg.

Without explicitly adding nvidia-pyindex, following the install commands gives the following (which includes nvidia-pyindex, so I am not sure why adding it explicitly is needed)

person@machine:~/transformer-deploy$ pip install ".[GPU]" -f https://download.pytorch.org/whl/cu113/torch_stable.html

I added wheel to the setup.cfg because otherwise the install command throws a lot of errors like this:
