fonts/R-systemfonts: import R-systemfonts-1.0.4

Provides system native access to the font catalogue. As font handling
varies between systems it is difficult to correctly locate installed
fonts across different operating systems. The 'systemfonts' package
provides bindings to the native libraries on Windows, macOS and Linux
for finding font files that can then be used further by e.g. graphic
devices. The main use is intended to be from compiled code but
'systemfonts' also provides access from R.
