Issue

When following the "Heterogenous Workers" example in the {targets} manual (https://books.ropensci.org/targets/crew.html#heterogeneous-workers), the following error appears:

Last error: controller for tar_make() must be a valid object of class "crew_class_controller" from the {crew} R package.

This seems to be a result of the validate_crew_controller() function. Should this function also accept crew_class_controller_group as a valid class?

targets/R/class_crew.R

Lines 243 to 254 in 384da1b

	validate_crew_controller <- function(controller) {
	tar_assert_inherits(
	x = controller,
	class = "crew_class_controller",
	msg = paste(
	"controller for tar_make() must be a valid",
	"object of class \"crew_class_controller\" from the",
	"{crew} R package."
	)
	)
	controller$validate()
	}

Yes it is supposed to work with controller groups, thanks for letting me know. Should be fixed now.
