TST: Avoid floating point errors in asinh ticker

greglucas · greglucas · commit 967d0e449b1d · 2022-04-16T09:30:59.000-06:00
This avoids the floating point issues with tests in the asinh tick
locator by moving away from the 100 log10 cliff. This was failing with
the new AVX instruction updates in numpy.
