Try to rebuild 1.14.3

I'm tying to revert the changes done in https://github.com/conda-forge/hdf5-feedstock/pull/231/

while keeping it updated with some recent improvements

Please discuss alternatives https://github.com/conda-forge/hdf5-feedstock/issues/240

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

Given the little activity in #240 I plan to merge this in 2 days.
