Linktest and SIONlib 2.0.0 are incompatible
The upcoming move of SIONlib to version 2.0.0. will break compatibility with Linktest as exposing raw SION file pointers will no longer be supported. When the new version of SIONlib is released we will need to rewrite the linktest output functions to be compatible. Alternatively users will have to install version 1.7.6. of SIONlib.
