Extend copyright output with raw data option

## Short Description

As discussed in the ORT Community Meeting (https://github.com/oss-review-toolkit/ort/wiki/ORT-Community-Meeting#2024-04-11) we propose to add a raw data export option to ScanCode so that post-processing of copyrights becomes possible on the raw and not normalized data which ScanCode usually does.

## **Describe the Update**

ScanCode should be able to export raw data on demand. Either as a second field as an addition to the existing copyright or as a configuration option to not normalize copyrights and provide the raw data in the existing result field.

## **How This Feature will help you/your organization**

We have a strong requirement from our legal department that copyrights need to be correct and complete. Some of the normalizations of ScanCode currently omit information which might be required. Therefore raw data would help us to do manual and automated post-processing of copyright statements.

## **Possible Solution/Implementation Details**

@pombredanne suggested to also export the existing raw tokenized data before normalization happens.
