Remove RJSONIO from HADES packages #43
Description
Related to work done in #42, we should aim to remove RJSONIO dependencies from HADES packages. Basing this on information I received from CRAN recently on RJSONIO:
Since more than 10 years the package was actually orphaned and given the long lists of reverse dependencies, the CRAN team decided to take over maintenance. We do no longer plan to maintain it further on and hence we are looking for a new maintainer. Please let us know in case you are interested. If nobody is interested, we will consider to orphan the package again and start the archival process.
