Rename yang filename to <module>@<revision> format

The O-RAN Alliance publish its yang modules with the filename format "<module>.yang".
For development purposes a filename in format "<module>@<revision>.yang" has the advantage,
that decisions by NetConf-Client and NetConf-Servers can be taken about compatibility and
API version without parsing the yang module.
This script parse the yang module for the latest revision and to rename the file accordingly.
