Preprocessing: Create profile functions have its own profile name definitions

[unndreay]

This is redundant. The functions should read the component names from components.csv instead and add "_profile" (analogously to building.infer_metadata()) to prevent errors.

Seen at create_hydro_reservoir_profiles(). Respective functions for solar, wind offshore, wind onshore contain even more redundant info.

More over, there is no error message, if the profile name cannot be found.

The only known error msg is for the file name ('resource'):

Indeed, the createprofile functions are in part redundant. Most them do the same thing - mapping the path of the profiles in the raw data to the naming convention to oemoflex. For all of those, a single update function together with a mapping would be the more efficient way. But components.csv does not help here I think, because it knows nothing about that mapping.

However, in some cases, some extra calculations are performed, e.g. in create_electricity_bev_profiles.

This is an issue of oemof.tabular, am I right?

[unndreay]

The initial explanation only addresses a tiny bit of what a solution with mapping can bring. Both the redundant profile identifier definition and the error msg can be solved by is solved with #92.
