text: Title: [FEATURE] add log_dtypes to pandas_utils
  Body: I might also want to log the `dtypes` between each step in a pandas pipeline. It's probably best to add a separate logger for both the `dtype` as well as the shape. 
  
  Should the column names be seperate too? Maybe worth a discussion. 
  
  It would also be nice if these features were documented on the documentation page together with some other `pandas_utils` functions.
