Feat: Add NZXT RGB & Fan Controller V2 and Smart Device V2 (USB PID 0x2019)

[rnoro]

Summary

Adds support for NZXT V2 controllers by implementing dynamic product ID detection instead of hardcoded V1-only support.

Fixes #80

Supported devices:

• ✅ RGB & Fan Controller V1 (0x2009) - existing support maintained
• ✅ RGB & Fan Controller V2 (0x2019) - newly supported
• ✅ Smart Device V2 (0x2019) - newly supported

Changes

• USBController.cs: Added RGBAndFanControllerV2 = 0x2019 enum value with comment "V2 / Smart Device V2"
• HardwareManager.cs: Updated device enumeration to support both V1 and V2 product IDs using array-based detection
• RGBnFC.cs: Modified constructor to accept dynamic productID parameter instead of hardcoded V1 ID

Implementation Details

• Replaced hardcoded USBProductID.RGBAndFanController with dynamic productID parameter
• Added supportedProductIDs array containing both V1 and V2 device IDs
• Maintained backward compatibility - existing V1 devices continue working unchanged
