The exported StringSet type is not necessary for the current use case of validating issues and audiences. The exported fields on VerifyOptions have been changed to require string slices. The collections package has been removed and the StringSet has been moved to the token package, where it is used. Signed-off-by: Stephen J Day <stephen.day@docker.com>
