🔀 Add utilities for vector

This introduces some new utilities for the vector type:

* Optional ostream utilities for debugging purposes,
* structured-bindings support for C++17,
* A `comparison_tolerance` member on each respective class to enable
  an easier upgrade path for custom tolerances

Additionally, this also modernizes the various vector sources, and
introduces a script to simplify modernizing future files.
