1.4.0

We are pleased to announce the 1.4.0 stable release of vt.

• With this new release of vt, we now support C++17 and begin a transformation to our interfaces to take advantage of the update. Bare handlers, object group handlers, collection handlers, and callbacks now can use parameterization to generate a message and marshal it into parameters for a remote handler. These generated messages will automatically detect if serialization is needed for any of the parameters and thus bypass serialization when not required.
• We have taken advantage of std::variant removing our pre-C++17 implementation and providing serializers for it.
