Excess parameters of energyConsumption assets

[smartie2076]

There are two parameters in energyConsumption.csv that are not needed:

• [ ] type_asset exists alongside to type_oemof. I think type_asset can be deleted from the list of necessary parameters and all input files.
• [ ] The parameter dsm exists but is of no relevance. This should also be deleted from the list of necessary parameters and all input files.

Could be tackled together with #375 @smartie2076

I think with new thermal asset needed the type_asset and type_oemof can prove useful:

for example: a CPH can be modelled as an oemof-solph transformer (type_asset="chp" and type_oemof="transformer") or as an ExtractionTurbine (type_asset="chp" and type_oemof="ExtractionTurbine")
