Dev test env python3.9

[ishaan95]

Testing code from the user guide by creating a new environment with conda. Key contributions -

• Test script in project root which runs code mentioned in the user manual.
• Environment file in project root for creating conda environment.
• Pip requirements file with working package versions. It's recommended to install shapely separately since it gives issues installing on Windows via pip. conda install Shapely=2.0.1 should work.
• The ideal setup is to create a conda environment using python=3.9, installing shapely as mentioned above, installing pip using conda install pip and then installing everything in the requirements file using pip.
