Stats Affected by Forks

[LRWeber]

LLNL forks from other LLNL repos end up multiplying certain statistics.

Activity is likely the biggest issue, but they could also affect repo counts for internal and external contributions, as well as ratios for licenses, languages, and topics.

See prior discussion in #295

From #415 I opened without looking first...

Noticed that we have forks of our own projects in other orgs.

E.g. https://github.com/visit-dav/spack and https://github.com/rose-compiler/spack are forks of https://github.com/spack/spack , all three are LLNL operated.

Maybe we can filter out the forks if we have the "parent" in the LLNL orgs already? (need the "parent": "full_name" from https://api.github.com/repos/visit-dav/spack)
