Add Subtitle Shifter Script to Shift .srt Timings Forward/Backward

Summary

Added a Python script that allows users to shift subtitle timings by a specified number of seconds (positive or negative). The script supports .srt files and saves the shifted subtitles as a new file.

Description

This script helps when subtitles are out of sync with the video. Users can provide the subtitle file path and the number of seconds to shift. The script uses the pysubs2 library (MIT-licensed) to handle .srt files safely.

The changes are as follows:

• Added subtitle_shifter.py to shift subtitle timings.
• Implemented CLI input for subtitle file and shift duration.
• Outputs a new .srt file with adjusted timings.
• Added simple checks for file extension and user-friendly prompts.
