fix #144 and #146 - module 'numpy' has no attribute 'warnings'

[izaanz]

Issue

Running the analyze() function in numpy versions that are >= 1.24 would cause the code to crash since the latest numpy release has dropped the np.warnings from their namespaces and the graph_numeric.py is still using it.

Fix

However, it appears that warnings is a built-in in Python thus we can use it without the np.warning and by simply importing warnings and using it directly without numpy. That's all, now we can use sweetviz with newer versions of numpy as well.
