Provide wheels for macos 11

To assist reproducing bugs, please include the following:

• Operating System: macOS 11.1
• Python version: 3.7
• Where Python was acquired: pyenv on macos, using via poetry
• h5py version (e.g. 2.6): 2.1.0 as required by tensorflow
• HDF5 version (e.g. 1.8.17): hdf5 locally installed with brew@latest
• The full traceback/stack trace shown (if it appears)

Since there are no wheels provided for macOS 11.1, h5py attempts to build locally and fails.

@reem Looks like homebrew’s latest hdf5 (1.12) is incompatible with h5py==2.10.0. Install 1.8 instead and make sure to set HDF5_DIR so the build can find it -

brew install hdf5@1.8

export HDF5_DIR=/usr/local/opt/hdf@1.8/  # default location, it's different if you have homebrew in a nonstandard place

then build with pip/poetry/whatever

[jlev]

I had to do export HDF5_DIR=/opt/homebrew/opt/hdf5@1.8
