MacenkoNormalizer not recognized when importing wsitiler.normalizer

[jeanrclemenceau]

If you run import wsitiler.normalizer as norm and try to instantiate an object like:
obj = norm.MacenkoNormalizer.MacenkoNormalizer(), then MacenkoNormalizer can't be found:

AttributeError: module 'wsitiler.normalizer' has no attribute 'MacenkoNormalizer'

However, if we import as import wsitiler.normalizer.MacenkoNormalizer as norm then we CAN call norm.MacenkoNormalizer()

I needed to add the functions within the MacenkoNormalizer.py to the normalizer module namespace within the __init__.py file.
