Update Install Docs to use 'setup.py' instead of build_pip_pkg.sh (which does not exist).

Here:

• https://github.com/tensorflow/graphics/blob/master/tensorflow_graphics/g3doc/install.md

and here:

• https://www.tensorflow.org/graphics/install

it says use build_pip_pkg.sh to install but that file is not in the repository. Seems like the user should instead do python setup.py

Needed this to install on OSX.

Also I needed to install openexr manually from source (v2.5.5) for both Ubuntu and OSX, I got compile errors otherwise, e.g. via pip install tensorflow_graphics or python setup.py

Also according to @podlipensky tensorflow_graphics_gpu is deprecated and should be removed from README.md

Also I had trouble with the OPENEXR installation so I had to install it from source and then tell the setup.py script to skip openexr. Here is my script in case it helps someone else. Requires one manual edit, see script. Safety not guaranteed:
