Manually add flextable latex dependencies to
the knitr session via knitr::knit_meta_add().
When enabling caching in 'R Markdown' documents for PDF output,
the flextable cached result is used directly. Call add_latex_dep() in a
non cached chunk so that flextable latex dependencies are added
to knitr metadata.
