feat: Support listing packages and their licenses via `packages check licenses`

[IchordeDionysos]

Description

Instead of just proving a simple output (Retrieved 10 licenses from 10 packages of type: MIT (10)), optionally allow users to list all licenses in a simple format.

e.g. very_good_cli package check licenses --list

And return something like:

Retrieved 1 licenses from 1 packages of type: MIT (1). (0.4s)

very_good_cli - MIT

Or a CSV-like format:

Retrieved 1 licenses from 1 packages of type: MIT (1). (0.4s)

very_good_cli,MIT

Requirements

• Allow to lit all analysed packages.
• All CI/CD checks are passing.
• There is no drop in the test coverage percentage.

Thanks @IchordeDionysos for opening this issue. I think it would be very nice if we enhance the reporting.

I was thinking having a reporter argument, so that other formats can be supported. For example:

very_good packages check licenses --reporter markdown

very_good packages check licenses --reporter csv

Would this be something you would like to work on? Let me know and I can assign it to you!
