Subject: [PATCH] test: migrate `math/base/special/asecd` to ULP-based testing

Replaces EPS-scaled relative-tolerance comparisons in the fixture
loops with ULP-difference assertions via `@stdlib/assert/is-almost-same-value`,
mirroring the pattern used in `math/base/special/asecdf` and `cotd`.

Final ULP bound: 1 (measured minimum; ULP=0 fails 887/6009 assertions,
ULP=1 passes all 6009 deterministically across repeated runs).
