Add XML files for Premiere Pro sequences and a converter script

- Created `05_02_Trim_clips_in_the_Program_monitor_1.xml` and `05_03_Sync_locks_and_track_locks.xml` to define video sequences with associated clips and metadata.
- Introduced `flake.nix` for managing dependencies and building the project.
- Added `premiere_to_resolve.py` script to convert Premiere Pro XML exports for compatibility with DaVinci Resolve, including video path updates and MP4 to MOV conversion functionality.
