Q2 weights from radiative-corrected Pythia6 are not correct

[c-dilks]

Environment: (where does this bug occur, have you tried other environments)

• Which branch (often main for latest released): main

Steps to reproduce: (give a step by step account of how to trigger the bug)

Check the Q2 distributions; this is added to the CI in #246

Expected Result: (what do you expect when you execute the steps above)

A distribution similar to ePIC, not radiative corrected:

Actual Result: (what do you get when you execute the steps above)

Here is ePIC, with radiative corrections enabled:

See artifacts from #246 for others; the best test is ePIC Arches (since the BryceCanyon files are too big)

@rseidl-rcf are we certain the radcor cross sections are correct?
