manage font working directory

Description

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().
