Copies an authenticated result tree from an rcynic run into the format
expected by most OpenSSL-based programs: a collection of "PEM" format
files with names in the form that OpenSSL's -CApath lookup routines
expect. This can be useful for validating RPKI objects which are not
distributed as part of the repository system.
