Can you rename this to older_than_days pls? I just had too read the code closely to understand what this param actually means because days is so generic it might as well be x, so I found a better name for it.

file to change: src/viadot/utils.py
task : anonymize_df

action: change var name from days to older_than_days

elif method == "hash": df.loc[to_hash, columns] = df.loc[to_hash, columns].apply( lambda x: x.apply(hash)

Not sure you want to do it this way -- python's built-in hash function does not generate the same output from the same input, so even if your data is the same, the calculated hashes would be different every time you run this function, which could be problematic for some use cases. To produce stable hashes, you need to use hashlib.
