Report main or test

Resolves #49, #44.

I decided to just treat *-tests.jar as ordinary jars like any other -- the only issue seems to be that their metadata lives in files based on the "base" jar filename.

TODO: Change COMPONENT_NAME in Utils.java, maybe by extracting the -tests fragment and appending it to the component name. The important thing is to not treat -tests as the version. Promoted to its own issue, #55.

Run on a cut-down dataset with just 3 compiler versions:

Frequencies for all metadata combinations, showing that we get a variety of combinations for both test and main scopes, indicating that metadata is being picked up correctly for test classes:
