DeffuantVector: Fixed bug in main.cpp

The multi-dimensional DeffuantVector model has a different AgentT
from the regular Deffuant model. Therefore, the model and simulation
have to be built with the DeffuantVector agent. This requires some
repititive logic in main.cpp.
Also fixed a small typo in the TOML input file for the DeffuantVector
model example.
