Enhancement required in CSV handling process

[messyblanket]

My experience:

• Load images and rods
• make changes to rods and save
• close the application and reopen
• repeat loading, changes and save.
• If you had not loaded the data_corrected folder for rods in the second round of loading, you have overwritten the work done in first round.

Suggestion: The function works in such a way that it looks for an existing corrected folder, checks if there is data in it and asks the user if that should be used instead. Suggestion 2: The program has a feature to save the previous state of GUI as the ability to restore previous session (the folders, the image numbers, etc.).

@dmitrypuzyrev @adithyaOvGu What are your thoughts on the suggestions?
