about attrib fails with duplicate about_resource

[goneall]

When running about attrib with an XLSX or CSV file containing duplicate values in the about_resource column, the following error occurs:

CRITICAL: The input has duplicated values in 'about_resource' field: ...

In this scenario, the resource is a container image which has several identified packages which point to the same file.

Do I need to generate unique names for each field or can the ABCTK be changed to allow duplicate about_resource fields?

[chinyeungli]

The current design is a one to one relationship. i.e one ABOUT file reference one resource. Therefore, no duplicate about_resource is allowed. However, there is also a scenario that we are generating attribution directly from an inventory without creating ABOUT files, the restriction or limitation maybe too harsh.

We need to remove this restriction if you are not creating ABOUT files.
