Blosc 1.10 fails to build from source when installed from `pip` (e.g. on Python 3.6)

WARNING: You are using pip version 20.2.2; however, version 20.3.3 is available.
You should consider upgrading via the '/tmp/venv/bin/python3.8 -m pip install --upgrade pip' command.

The problem is that the way pip figures out the build dependencies is by importing setup.py... but setup.py import scikit-build, thus blowing up before pip can figure out that it needs scikit-build installed.

(I hit this because my install for some reason didn't find the macOS binary wheel, so it fell back to tarball build, not sure why that happened.)

Ah, the reason I hit source build is because I installed on Python 3.6, and Python 3.6 doesn't have a binary wheel available. I updated the title.

Thanks for bringing this to our attention. This should have been fixed in the new 1.10.1 release.

Thank you!
