build fails with mpi4py 3.1

See original GitHub issue

setup.py mandates mpi4py 3.0.3,

SETUP_REQUIRES.append("mpi4py ==3.0.3; python_version>='3.8'")

But the latest release of mpi4py is 3.1.1, so h5py will not build on systems where mpi4py 3.1.1 is installed. Stack trace with mpi4py 3.1.1 installed is

ERROR: Exception:
Traceback (most recent call last):
  File "/usr/share/python-wheels/resolvelib-0.5.4-py2.py3-none-any.whl/resolvelib/resolvers.py", line 171, in _merge_into_criterion
    crit = self.state.criteria[name]
KeyError: 'mpi4py'

Is there a reason for the strict 3.0.3 version? As far as I can see mpi4py 3.1 should be fine. Patching to

SETUP_REQUIRES.append("mpi4py >=3.0.3; python_version>='3.8'")

works, h5py builds and tests pass.

Operating System: Debian GNU/Linux (debian unstable)
Python version 3.9.7
Where Python was acquired: debian repository (apt-get install python3)
h5py version 3.3.0
HDF5 version 1.10.7
