Revert C++17 usage of std::exclusive_scan

* Unfortunately on some systems such as the Nvidia Jetson, while the
  compiler supports C++17, the STL implementations are incomplete.
  One such missing implementation is std::exclusive_scan, so this
  patch reverts to the old way of manually computing prefix sums.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.
