bundle IDS citation style as ids.csl and make it the default
Include the IDS citation style (based on the style developed for
ICLC-10 2023 in Mannheim) as resources/ids.csl and pass it to pandoc
unless the document specifies a csl of its own. Drop the now-redundant
remote csl URL from examples/ids.Rmd.
