Add examples from ETCS working group documentation to wiki page CO:speedProfile
The ETCS working group has created a documentation for speedProfiles. Only a small part of this documentation was taken over to the railML 3 wiki. In particular the extensive example was not included in the documentation. This should be corrected after a review by the ETCS working group.
Documentation in question: https://cloud.railml.org/f/89853 Wiki page: https://wiki3.railml.org/wiki/CO:speedProfile
