CycloneDX CLI seems to output invalid BOM when license exists with empty name

We started getting validation errors for `merge`d BOMs recently, that the license schema was invalid:

> #/components/152/licenses/0/license: Expected 1 matching subschema but found 0

Upon inspection, this is because the BOM generated by cyclonedx-cli has components like this:

(As a side issue, the Chinese characters are not handled correctly)

This is in violation of [the spec](https://cyclonedx.org/docs/1.4/json/#tab-pane_components_items_licenses_items_license_oneOf_i0), where each license must have a name or ID.

The source BOM which instigated this has the following component:

This is not correct either, but cyclonedx-cli could handle it more gracefully. The expected behavior would be for merge and convert to take license arrays like the above and generate `"licenses" : []` from them, instead of empty license objects.
