Metadata-only patch after the V1.0.1 Zenodo record, which was cut while DESCRIPTION still said 0.1.0. The licence is declared as CC BY 4.0 with LICENSE.md; CITATION.cff and inst/CITATION carry the Zenodo concept DOI and declare the work as a dataset; DESCRIPTION gains keywords and the spatial and temporal coverage; the dataset documentation matches the data; Lars Schöbitz takes over as maintainer, Yash Dubey stays as author; the pkgdown site is deployed from gh-pages; R CMD check runs in CI on dev and main. The data are unchanged.
