Maybe add JSON::Path and/or Data::Visitor as dependencies

There are a couple of cases where a deep data structure needs to be traversed or searched. This can be done by a recursive subrouting. Alternatives would be using a query language or employ the visitor pattern.

libjson-path-perl is not in Debian Buster. Putting the module into Kernel/cpan-lib remains an option.
