Description

Legacy Kraken support added. Due to their limited functionality, I've implemented limits for these devices for fixed speeds only (fan & pump) and added a startup warning about a potential driver conflict with the EVGA CLC model.

I'm waiting on a successful test with a real device if possible, before removing the WIP status.
