Description

In the Hyper-V environment, there's an observed behavior where pfSense does not appear to search for config.xml files for the External Configuration Locator (ECL) within CD/DVD drives. Given the limitation in Hyper-V where virtual USB drives cannot be mounted natively, adding support for reading from CD/DVD drives for ECL would provide a valuable solution to this challenge.

Steps to reproduce:

Setup a pfSense instance on Hyper-V.
Create an ISO with the required file structure (/config/config.xml).
Mount this ISO using the virtual disc drive in Hyper-V.
Boot the pfSense instance and observe that pfSense ignores the config.xml found within the CD/DVD drive, indicating that it doesn't search CD/DVD drives for ECL files.

Benefit:
Introducing this feature would empower Hyper-V users to utilize the External Configuration Locator via CD/DVD drives, offering an alternative solution to the USB limitation and enhancing the usability of pfSense in Hyper-V environments. Without this functionality, I am unable to deploy pfSense automatically at scale without modifying the original distribution ISO, which I would prefer to avoid.

and this isn't working as expected. The code in find_config_xml() loops through the slices, but a standard ISO image with the config does not have slices, so it is ignored. A simple fix is to add a special case in the get_disk_slices function to return CD devices directly.

The code should also check for format type cd9660 instead of iso9660.

I should have a pull request together soon to address both of these issues.
