Enhancement request: Support adding the VCS and similar URLs from ScanCode.io scan results to packages

[rogu-beta]

Is your enhancement request related to a problem? Please describe.
Currently ScanCode.io already provides information in its scan results, if it finds them, such as:

• homepage_url
• bug_tracking_url
• vcs_url

These do not seem to get imported into DejaCode.

What are the benefits of the requested enhancement?
Users would have all the information directly available in DejaCode. Given that packages already have fields for the VCS, homepage, and bug tracker, it seems like a sensible step to insert the informationen provided by ScanCode.io when available.

Describe the solution you would like
Once the scanning is concluded and the packages entries are being created in DejaCode, it should use the aforementioned fields in the scan results to add them to DejaCode's data model of the respective package.

Additional notes

This may still be relevant for those that do not use PurlDB, but PurlDB does mostly solve this for us.

@tdruez Thank you for your work on enhancements! Just to make sure, can "Improve Packages from PurlDB" still be applied potentially overwriting results by ScanCode.io and will this ensure that manually modified data is not overwritten on subsequent scans?
