Describe the feature you'd like to see

Please give a clear and concise description and provide context why the feature would be useful.
Also, we'd appreciate any implementation ideas and references you already have.
The temporal aggregation of time dependent data and snapshots in the model is currently included in prepare_sector_network. However, it makes sense to separate this into a separate rule.
Tasks:

• Refactor prepare_sector_network to separate temporal aggregation into its own subsequent rule
• Check if it is possible to change the input of time_aggregation from "networks/base_s_{clusters}elec{opts}.nc" to "networks/base_s_{clusters}{opts}{sector_opts}_{planning_horizons}.nc". This way, the segmentation option will be able to work again on time dependent data that is only added in prepare_sector_network. The issue is documented in [PARENT] Time aggregation with segments (SEG) requires some time dependent data #343
