liboqs-cpp version differs from libqoqs-version

[embetrix]

when building the liboqs-cpp with new liboqs version 0.13.0 I get the warning:

Warning! liboqs version 0.13.0 differs from liboqs-cpp version 0.12.0
liboqs version: 0.13.0
liboqs-cpp version: 0.12.0

maybe bump up the liboqs-cpp version also to 0.13.0 ans set a new tag ?
