Add constructor method for ADLChargeDriftModel (and others)

[lmh91]

Right now the ADL charge drift model is usually constructed from a configuration file.

I think it would be nice to also have a constructor function for it,
which takes all the parameters, e100μ0 ..., as keyword arguments
(defaults would be the values from the ADL paper(s) which we can update once we have better ones).

The current method taking the configuration-file (dictionary) as input should than just pass the values to that keyword constructor method.

Same for the temperature model constructors.
