Kerchunk conda package should pull in `h5py`

[valeriupredoi]

Hey guys, we're installing kerchunk in our conda/mamba environment, and I was expecting h5py, as a direct dependency of kerchunk, to be pulled in by the package at install point - proves out it's not the case, could you do that please, and make sure that all the direct dependencies are pulled in when you build your conda package? See eg a failed test showing that. My apologies if I should open this at your conda feedstock GH repo, but I couldn't find it - also, let me know if I can help with this, I can open a PR, and cheers muchly for your good work on Kerchunk overall 🍺

Nevermind my blabbering, I found the feedstock repo where this issue should live 😁 conda-forge/kerchunk-feedstock#4
