Overview

Merges together a list of example statuses from this run and a list from previous runs (presumably loaded from disk). Each example status object is expected to be a hash with at least an ‘:example_id` and a :status key. Examples that were loaded but not executed (due to filtering, –fail-fast or whatever) should have a :status of UNKNOWN_STATUS.

This will produce a new list that:

- Will be missing examples from previous runs that we know for sure
  no longer exist.
- Will have the latest known status for any examples that either
  definitively do exist or may still exist.
- Is sorted by file name and example definition order, so that
  the saved file is easily scannable if users want to inspect it.
