Subject: [PATCH] test: migrate `stats/incr/hmean` to ULP-based assertions

Replaces the relative tolerance assertion in the `stats/incr/hmean`
accumulator test with an ULP difference assertion using
`@stdlib/assert/is-almost-same-value`. The measured maximum ULP
difference over the test data is 1, which is the minimum bound which
passes (0 fails).
