Information about Face Output

[RiRyuichi]

Edited Person.msg, rosOpenposeAsync.cpp and rosOpenposeSync.cpp files, and run with text = [facePart.pixel for person in msg.persons for facePart in person.faceParts] in run.lauch. to output coordinates of face key points. Please refer to https://github.com/ravijo/ros_openpose/issues/73#issuecomment-1305251719

It looks all right. I am going to merge this pull request assuming it doesn't break existing functionality. Thank you very much.
