Add support for running on Colab

[dzlab]

I'm not able to install this library on Colab. I tried this

git clone https://github.com/punica-ai/punica
cd punica && pip install .

But this is failing with the following error

Processing /content/punica
  Installing build dependencies: started

  note: This error originates from a subprocess, and is likely not a problem with pip.
