Include tsan_annotations.h so the TSAN guard in timing_test works - #85

Conversation
timing_test.cpp wraps its whole body in #if !DISPENSO_HAS_TSAN, but that macro is defined in dispenso/tsan_annotations.h, which the file never includes. The macro has therefore always been undefined, !0 always true, and the guard has never excluded anything -- the timing tests have been compiled in under TSAN since the file was added. Adding the include restores the intended behaviour. Nothing changes outside TSAN builds.

Fixes #88.
tests/timing_test.cppwraps its entire body in#if !DISPENSO_HAS_TSAN, with acomment explaining that timing assertions are too sensitive to instrumentation
to be meaningful under ThreadSanitizer.
DISPENSO_HAS_TSANis defined indispenso/tsan_annotations.h, which the testnever includes. The macro is therefore always undefined,
!0is always true,and the guard has never excluded anything — the timing tests have been running
under TSAN since the file was added.
Adding the include restores the intended behaviour. Nothing changes outside
TSAN builds.
This is invisible in the normal build because the CMake configuration does not
warn on undefined macros in
#if. Building with-Wundefsurfaces it.
