library __init__ uses a relative path which makes pip install fail

Hi!

This is for Issue #38: https://github.com/openfheorg/openfhe-python/issues/138.

• PEP8 recommends absolute imports but says relative usually work. This case, importing a local .so file, is where they can fail.
• Examples Keras and (PyTorch)[https://github.com/pytorch/pytorch/blob/main/torch/__init__.py#L1582].

HTH, Drew

it was failing for me as well; I had to build the package with sdist and manually copy over to python install area for it to work
