Should license information be available for NONE and NOASSERTION ?

[pmonks]

In SPDX 3.0.2, the IndividualLicensingInfo values NONE and NOASSERTION are becoming closer to behaving like any other license id, but currently the following code does not return any results:

org.spdx.library.ListedLicenses.getListedLicenses().getListedLicenseById("NONE");
org.spdx.library.ListedLicenses.getListedLicenses().getListedLicenseById("NOASSERTION");

The question is: should it be possible to get the metadata (name, description, etc.) for these "identifiers", and if so how? They're not listed licenses, so perhaps they should be looked up via different methods and/or classes, for example?

Note: I have no specific need for this functionality myself; it was just something I noticed in passing, as I worked on implementing some of the changes in SPDX v3.0.2.
