Clarification of license

[NCommander]

Would you consider adding a specific license (ideally a permissive one like two clause MIT (https://choosealicense.com/licenses/mit/) to this project?

I'm currently working on my own version of scanning COVID cards (albeit with a broader scope), and if there are others who may want to fork or use this, having explicit licensing helps a lot. If you choose to do so, just include the text of the license as a file in the core of the repo, and set it on GitHub. It really does make a difference for others.

Thank you for this awesome project.
