Data structure of Crawler

[Brend-Smits]

The data structure of the crawler should be reconsidered and possibly adjusted. Currently, it breaks compatibility with existing crawlers from other implementations from the Inner Source Commons group.

This is also why the portal is not yet compatible with data from other crawlers. This makes adoption more difficult.

In this issue, we should investigate if breaking from the data structure of the existing crawler is needed or not. We might be able to fit custom data in the dynamic object from the Inner Source Metadata file.

In case the data structure is changed, the portal will also need updating.
