Improve driver injection by mounting WIMs

Browse Source 
Replaces the slow WIM extraction process with a faster WIM mount operation. This significantly improves performance when injecting drivers from a WIM file.

The script now properly unmounts the WIM after injection to ensure resources are cleaned up correctly.

Additionally, log messages are now written to the console for better real-time feedback during script execution.
