Update requirements.txt and fix issue when rendering video with subtitles

In moviepy version 1.0.3, CompositeVideoClip is a module within
moviepy.video.compositing. To use it correctly, we need to import the
CompositeVideoClip class from the module.

This commit makes the following changes:
- Update the import statement for CompositeVideoClip in videoclipper.py
  to import the class from the module.
- Fix the moviepy version to 1.0.3 in requirements.txt to avoid unexpected
  behavior due to version upgrades.

These changes resolve the issue encountered when rendering videos with
subtitles using moviepy 1.0.3.
