fix: don't raise in case we encounter modules we don't know

Fixes #62

Should we just accept any module values instead of checking that they belong to the list?
Then we don't have to change this when a new flatbuffer schema is added.

Yes, makes sense! Should we include the number of skipped modules per category in the final report? Or just print a message?

I'm thinking we don't show anything about the ignored modules, module is not part of the nexus standard anyway so it makes sense that we don't check them, it should not be expected that we do. If we know how to check those entries anyway that is of course useful, but it's just a bonus.
