Commander ST fw 2.x: liquidctl workaround

Commander ST fw 2.x (tested on Corsair iCUE H170i ELITE CAPELLIX AIO) — single-shot apply workaround

A standalone Python script for users hitting either of these symptoms on a Corsair Commander Core / Commander ST running firmware 2.x:

  1. liquidctl set <ch> speed T P T P … fails with IndexError: index out of range — _read_data hard-codes three HID read chunks (~181 bytes) and the device's full curve table for 7 channels at 7 points each exceeds that.
  2. liquidctl status (or any set) times out after ~5-25 invocations, only recovers with usbreset — the device's firmware silently stops responding to HID after a burst of operations, while the USB stack and kernel hidraw layer remain healthy (dmesg is silent during the failure; lsusb -v still works).

Tracking issue: liquidctl/liquidctl#753.
