Refactor Macro_NLU_Entity_Refinement.ipynb to update the dataframes for the removed and complete data sets

[AmateurAcademic]

Description

The current flow updates only the dataframe where removed entries are considered. While the dataframe that contains all the removed entries only is important for training and testing both the intent and entity models, we want to create a complete data set tracking all the entries, similar to Macro_NLU_Intent_Refinement.ipynb. This issue is realted to #4

DoD

• Create a CSV for the updated entity refinement entries with the refined intent entries
• Update the code in Macro_NLU_Entity_Refinement.ipynb to load the above dataset and update this data set
