DM-21738 showed that the correct way to write a copyright statement for AURA is:
Association of Universities for Research in Astronomy, Inc. (AURA)
DM-21738 is updating the Developer Guide; this ticket updates copyright statement templates in https://github.com/lsst/templates
Put Dual License on pex_config so it can be distibuted under bsd clause 3.
See AURA copyright updates in this templates PR: https://github.com/lsst/templates/pull/58
Thanks for doing this.
