Added SLEquipmentConfigurationMessage

I am not documenting this in the readme just yet because I don't really know how to interpret the data provided, but it seems to be necessary if we want to be able to change pump speeds in the future or read any historical data about the equipment. I'm not sure how much I'm going to be able to figure out about these arrays since the data appears random to me at the moment, but perhaps others will be able to figure out what's in here.
