Initialize or remove font directory used to store downloaded font files.
This directory is managed by R function R_user_dir() but can also
be defined in a non-user location by setting ENV variable GDTOOLS_CACHE_DIR
or by setting R option GDTOOLS_CACHE_DIR.
Its value can be read with the fonts_cache_dir() function.
The directory can be deleted with rm_fonts_cache() and
created with init_fonts_cache().
