Pull Request: Add Support for Offline Catalog Files in OSD Software

This update introduces support for using offline catalog files in the OSD environment, enhancing flexibility for scenarios where the default OSD module cache may not be suitable.

Background

Since mid-April, daily OSD module updates have included OS and DriverPack catalog files (JSON and XML) under the cache folder. These updates ensure access to the latest download information.

However, some users may require customized or alternative catalog files. To support this, the update allows placing user-defined catalog files in the USB\OSDCloud\Catalogs folder.

Key Features

• Offline Catalog Support: Users can now override the default cache by placing their own catalog files in the Catalogs folder.
• URL Validation: To prevent issues from outdated or invalid URLs in custom catalogs, a curl-based validation step has been added. This has proven effective in internal testing.
• Non-Intrusive: This change does not affect normal operations unless the Catalogs folder is explicitly created.

Request

Please consider merging this enhancement into the master branch of the OSD project.

This looks excellent, and since you're only excluding C: from the search path, it should work with network boot scenarios where no USB drive is present (ie. embedded in the boot.wim at X:\OSDCloud\Catalogs).

I would love to be able to define custom paths such as the following, and then leverage the "not yet implemented" cache host variable (see #272), which looks like something we could do with this patch:
"Url": "{HOSTNAME}/OSDCloud/OS/24H2-latest.wim"
