[Qa-debsources] Return source package for given binary package

[deffo at gmx.de]

Hi there,

in a few cases, it is necessary to know the source package of a given binary package, for example when handling CVEs, which are based on the source package. I did not find a liable source to get this information programmatically, apart from scraping the information from https://packages.debian.org/de/sid/<binary package name>. Would it be possible to add a API
function that returns the source package for a given binary package? Or does this already exist?

Best regards
