CsvReportRenderer to support Multiple Licenses

[choweiyuan]

Similar to #291, I'd like to see CsvReportRenderer to show multiple licenses if possible.

Motivation - libraries such as https://github.com/qos-ch/logback?tab=License-1-ov-file is dual licensed. Current CsvReportRenderer - https://github.com/jk1/Gradle-License-Report/blob/master/src/main/groovy/com/github/jk1/license/render/CsvReportRenderer.groovy#L89C102-L89C125 only gets one license (lastOrNull https://github.com/jk1/Gradle-License-Report/blob/master/src/main/groovy/com/github/jk1/license/render/LicenseDataCollector.groovy#L27)

I think it'd be more accurate to show multiple row of licenses in that scenario

I also found the choice of lastOrNull a bit arbitrary. Especially in light of using the checkLicense task along with a JSON that lists my allowed licenses, I will get a pass run, along with a report output that lists licenses that I do NOT allow. E.g. ESAPI has a BSD license for the code (which I allow), but also lists a CC BY-SA license for "content", which I do not allow. Since the latter is last in the list, it will be reported.

What about adding a filter that also parses the allowed-licenses JSON and uses it to prefer licenses in there for reporting? Maybe a bit "magic", or then, at least have a filter or renderer config that allows specifying another JSON that lists all licenses in order of preference? Not sure what's best, but you see the problem?
