Workaround rtd 2 (#106)

* rtd config file v2

* let's try pip again

* fix version pinning (pip)

* avoid build zarr wheels + fix toolz missing

* try install more deps using pip

* try conda default channel and less deps with conda

* need zarr 2.4, reinstall with pip

Since not available on conda default channel
