Subject: [PATCH] Title: Add local caching for large ISO files with
 pre-fetching logic

- Modified internal/op/driver.go to enhance driver configuration handling, ensuring proper support for new caching behavior
- Added logic to block requests for ISO files >10G, pre-cache first 30M and last 5M locally before proceeding
- Implemented conditional request routing: serve from local cache if content is available, otherwise fall back to remote storage

Improved local file access efficiency for large ISOs by introducing intelligent pre-caching, reducing latency and bandwidth usage during initial access while maintaining compatibility with existing drivers.
