Add type parameters for dispatching based on transmission and device model type

[coroa]

The type parameters should live on either the main EnergyModel or the individual components. One should be able to switch between the different models, ie rebuild the same netcdf-based model as unit-commitment, econ-dispatch with lin opf kirchhoff/lin opf angles/ac opf/copperplate.

Also include a device type parameter to differentiate between expandable and fixed generators
