Subject: [PATCH 2/2] CI: avoid running slow tests in wheel builds and
 Emscripten

These are extra tests that iterate over all wavelets and require a lot
of time even on a regular x86-64 build (~10s for `test_precision`, 42s
for `test_swt_iswt` on my machine). For Emscripten and especially under
Qemu (Linux aarch64 wheel builds) they're really really slow.
These tests aren't essential to run for wheel builds, so disable them.
