Web API support

[sasalatart]

Hey, I am thinking about creating an "official" web client that provides access to open-sir without the need to install the CLI, and also as a tool to be used by people who are not familiar with the terminal nor with Python.

In order for it to work, it would need the following:

1. The ability to install open-sir via pip install, even without having the code locally.
2. Provide the open-sir CLI with a command to print the plots present in feat(model): plot #80 to stdout as SVG, or something like that, so that I may pipe them as an http response.

Is there anything else you would be interested in adding to it?

Great! I think I can work with @jia200x on the plot part, while making open-sir installabe through pip install goes a bit ot of my scope but I would be happy to learn how to do so, so I can collaborate
