Code Refactor: Remove Pandas as a dependency by using the natively in built csv module instead

[dzumii]

Description
Code refactoring to remove Pandas from the tracking functionality and implement the functionality using built-in Python libraries.

Changes Made

• defined read_csv function to read CSV files using the native CSV library.
• Replaced some other pandas data manipulation.
• Adjusted the stats function to calculate statistics using the statistics library.
• Adjusted the get_file_size function

Status

• The tracking functionality works with the changes.
• Time taken is now a bit shorter.
• However there are still some inconsistencies in the outcome in comparison with the outcome generated using the tracking functionality with pandas, particularly relating to the file_size and stats functions.

To Do

• Refine the check_types function.
• Refine the get_file_size function.

This is still a Work In Progress
Comments and suggestions would be really appreciated

Related to #1090

Closes #1054

@dzumii could you also share before and after results? That is, results from the master branch and your work?

@DhanshreeA, I have been able to finally fix the inconsistency in the mismatch_type ,thanks to @Malikbadmus,took us some hours to crack

here is the comparison between the two metric files when i run
diff -y <txt-file-generated-from-master-before-changes> <txt-file-generated-after-removing-pandas>

I also noticed a warning when i try to close a model having used the track flags

Hey @dzumii Could you please report this in an issue (the warning) and we can tackle it there?
