Improve installation process

[AntonPetrov]

• Improve documentation (split docker/singularity info into tabs, remove unnecessary steps like docker pull or verifying installation)
• Develop a python wrapper that can be installed with pip and that would run docker/podman/singularity commands behind the scenes
• Remove precomputed library Do not require users to install precomputed library #151

Other ideas:

• Consider dockerless distributions with all dependencies bundled in. PyInstaller, cx_Freeze, Py2exe, PyInstaller and Py2app would be good options
• Consider bundling everything in a conda environment and distributing it might be a good choice for conda-inclined folks
• Wrap in an electron app
• WASM?
