This commit also adds support for the sensors of the MPS Flow devices, as they have the same USB product ID and sensor layouts. Implemented by Leonard Anderweit [1]. Internal and external temp sensor readings are available, along with the flow sensor. Additionally, serial number and firmware version are exposed through debugfs.
