Fixes #323

Type of change

Bug fix (non-breaking change which fixes an issue)
Documentation Update

1. pytube: The official pytube package frequently breaks due to changes on YouTube's side. To address this, I replaced it with pytubefix, a maintained fork that resolves these issues and is a drop-in replacement.

2. moviepy.editor: Importing moviepy.editor raised a ModuleNotFoundError in environments using newer versions of MoviePy. This is likely due to changes in the structure of the MoviePy package introduced in versions 1.0.3 and above, where some modules (including moviepy.editor) have been restructured or removed. These changes can cause compatibility issues in environments using updated MoviePy versions.

Changes Made

• Replaced:
  import pytube
  with:
  import pytubefix as pytube

  from moviepy.editor import *
