The testProtoFromKiCadObject function called Clone() on a KiCad object
and copy-constructed from the result without ever deleting the cloned
object. Fixed by wrapping the clone in a unique_ptr so it is
automatically deleted after the copy construction.
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
