=== Improvements ===
* Further reduced allocations
* The compact, console, TAP and XML reporters perform less allocations in various cases
* Removed 1 allocation per entered `SECTION`/`TEST_CASE`.
* Removed 2 allocations per test case exit, if stdout/stderr is captured
* Improved performance
* Section tracking is 10%-25% faster than in v3.3.0
* Assertion handling is 5%-10% faster than in v3.3.0
* Test case registration is 1%-2% faster than in v3.3.0
* Tiny speedup for registering listeners
* Tiny speedup for `CAPTURE`, `TEST_CASE_METHOD`, `METHOD_AS_TEST_CASE`, and `TEMPLATE_LIST_TEST_*` macros.
* `Contains`, `RangeEquals` and `UnorderedRangeEquals` matchers now support ranges with iterator + sentinel pair
* Added `IsNaN` matcher
* Unlike `REQUIRE(isnan(x))`, `REQUIRE_THAT(x, IsNaN())` shows you the value of `x`.
* Suppressed `declared_but_not_referenced` warning for NVHPC (=2637)
=== Fixes ===
* Fixed performance regression in section tracking introduced in v3.3.1
* Extreme cases would cause the tracking to run about 4x slower than in 3.3.0
