`pip install` fails on fresh `python==3.11` and `python==3.10` conda environment

[kamurani]

On a clean conda environment created with conda create -n env_name python==3.11 on Linux, and then

pip install graphein 
graphein

I get the following:

Appears that the try: except: wrapper around the import statement isn't doing what it's meant to? Nothing mentioning rdkit was picked up in the pip install as far as I can tell.

# graphein/molecule/atoms.py
try:
    import rdkit.Chem as Chem
except ImportError:
    import_message(
        "graphein.molecule.atoms", "rdkit", "rdkit", True, extras=True
    )

Note: this occurs when using python==3.10 as well.

Thanks for flagging. I think pip install rdkit will do the trick for now. Looks like there are some imports that need to be caught and some better logging too.
