Add VoodooI2C plug-ins

[yjmd2222]

Hi. Can you add VoodooI2C plug-ins separately? It seems the build-repo builds VoodooI2C and the plug-ins at respective commits specified in the VoodooI2C repo. The latest changes to the plug-ins are not built until VoodooI2C developers decide to bump and release the whole kext, which is when they also update and checkout the submodules to the latest commits, which are then picked up by the build-repo. So maybe the build-repo can detect changes in the submodules and update them before building? Or build as is and then build with the latest submodules and upload them both? tyvm.
