Merge branch 'develop' into enh/discretize-isa-from-2k

Resolve conflicts in favor of develop for structure, preserving the
pressure_ISA discretization change (#1056):
- CHANGELOG.md: move the #1056 entry to the [Unreleased] > Changed
  section (it is not part of the released v1.13.0).
- test_flight.py: adopt develop's npt.assert_allclose(atol, rtol) style;
  merged freestream values stay within rtol=1e-4.
- test_environment.py: keep both the new ISA discretization test and
  develop's pressure-conversion-factor tests.
