osub External File Handling

Current Behavior of osub
Currently, osub doesn't automatically copy external files referenced in ORCA input files to the local scratch directory. 
As a result, calculations that rely on these files may fail.

Recommended Solutions
To avoid errors when referencing external files, please use one of the following methods:
1. Use the -N option:

osub -N input.inp

2. Specify files using absolute paths.

Future Improvement
We're planning to implement automatic detection and copying of external file references in the future. 
For now, please be aware of these limitations when using the system.
