Description
This PR adds support for the ASUS ROG Ryujin III EXTREME AIO cooler by extending the existing Ryujin II driver implementation.
The changes are based on my previous work reverse-engineering the Linux kernel driver driver for this device. Since the Ryujin III EXTREME uses a very similar protocol to the Ryujin II, I was able to adapt the existing driver with minimal modifications. The main differences are that the Ryujin III EXTREME lacks the fan control capabilities present in the Ryujin II, and it requires controlling the fan and pump duty on channel 1 instead of channel 0. These variations required adding some conditional variables while keeping the rest of the protocol implementation intact.
Please let me know if you need any more changes from my side to merge this PR.
