v0.2.0-rc6: 6th RC for CRAN submission test This is the sixth release candidate to be submitted to CRAN. The purpose of the v0.2.0 release is to ensure that `calendRio` meets the CRAN requirements before moving towards a 1.0 release that actually adds functionality on top of the upstream `calendR` package. Release candidates are tagged on the corresponding release branch (branched off from the development branch) before merging to the main branch. This allows for additional fixes before the actual release. Once the new version was successfully submitted to (and accepted by) CRAN, the release branch is merged to the main branch and the resulting merge commit is tagged as release. This RC addresses all remarks by CRAN reviewer Julia Haider concerning `calendRio` version 0.2.0-rc5. Changes since v0.2.0-rc5: * Documentation: * Remove CRAN reviewers from author list
