Eigen::Matrix::cast<ceres::Jet>() not needed if upgrading to Eigen 3.3

An upgrade to Eigen 3.3 will make it innecessary to add all these cast<T>() after each Eigen matrix or vector when coding Fectors with Autodiff.

This issue is an orange light for an upgrade to 3.3.

created merge request !324 (merged) to address this issue

mentioned in merge request !324 (merged)

To upgrade, one only needs to install Eigen-3.3 and recompile + install ceres-1.14.

This would be, to be more specific:

1. Install Eigen 3.3
2. Compile Ceres 1.14 with the new version of Eigen (do not change the order of these operations!)
3. Install Ceres 1.14
4. Compile wolf
