[REQ] Option to merge or overwrite folders/files with the same name during extraction

### Is your feature request related to a problem? Please describe
Currently, when extracting multiple archives that contain a parent folder with the same name, Keka automatically renames the subsequent folders by adding a numeric suffix (e.g., Folder, Folder 2, Folder 3). I would like these archives to be extracted into the same parent folder (It's like I'm using `tar -zxvf` in the terminal to extract these archives in turn) rather than creating multiple separate ones.

### Describe the solution you'd like
Provide a prompt or a default setting to overwrite or skip or create a new folder if individual files/folders have the same name.
