More flexibility

Hi,

I'm using Corsair Commander Pro and have been running liquidctl on a Windows VM.
A couple of days ago I found your docker and installed it. Works great but I had to edit run.sh to match my system

#! /bin/bash
liquidctl initialize all
liquidctl list
liquidctl set sync speed $FANSPEED

if [ ! -z "$COLORSPEC" ]; then
   liquidctl $COLORSPEC
fi

sleep 20
while true; do
        liquidctl status
        sleep 15
done

More options in the container settings would be great, and thank you for the docker.
