devel/R-crayon: Import version 1.3.4

Colored terminal output on terminals that support 'ANSI' color and
highlight codes. It also works in 'Emacs' 'ESS'. 'ANSI' color support
is automatically detected. Colors and highlighting can be combined and
nested. New styles can also be created easily. This package was
inspired by the 'chalk' 'JavaScript' project.
