Create report of all dependencies with their license

[digulla]

Add an option to get a report of all dependencies with their license, ideally as HTML but text would be sufficient, too.

The report should include the name of the dependency, the version and the first matching license name from authorized_licenses plus the status OK.

If there is no match, it should look for a match in unauthorized_licenses. If there is one, the dependency should be reported as UNAUTH.

If there is no match, the status should be UNKNOWN

Just an FYI, pip-licenses can do part of this generation already.
