Change current DeviceTypes into DeviceInterfaces

[Dantali0n]

DeviceTypes in terms of radiological devices is quite vague and does not clearly indicate that it implies the communication interface for a device. Instead DeviceInterfaces would be a better indicator which would than subsequently allow DeviceTypes to be used more effectively.

For instance, DeviceTypes could be used to distinguish between geiger counters, proportional counters, scintillation devices or semiconductor based counters. This distinction is quite important as it allows to associate certain types of radiation measurements with devices.

As an example, Geiger counters can not accurately measure absorbed dose as they do not proportionally measure the energy of each count (event). While a dosimeter will sometimes only measure effective and or equivalent dose and not have any way to report absorbed dose.
