[FEATURE] Move the fileutil to stream package

[kaduartur]

- What I did
Extract the fileutil to stream pkg:

• Created a new package named the stream.
• Created a file named dir.go to manipulate directors of the operational system.
• Created a file named file.go to manipulate files of the operational system.
• Created a file named stream.go to helper to manipulate .zip files.

- How to verify it
Run make test
