Append a risk-of-bias traffic-light plot to a forest plot

A wrapper for metafor::forest function, which adds a risk of bias traffic-light plot to the right-hand side of the forest plot. The heavy lifting for this function is done by metafor. Note that if not specified as additional arguments, this functions sets the header argument of metafor::forest() to TRUE.

rob_forest(
  res,
  rob_tool = "ROB2",
  rob_me = NULL,
  rob_levels = NULL,
  title = NULL,
  rob_legend = TRUE,
  rob_legend_cex = 0.9,
  ...
)
