Correct Total System Costs Calculation

[toniseibold]

Replace the function get_economy with a more detailed calculation of the energy system costs of one region.

get_tsc(n, region

• calculates the opex and capex and grouping them by name and carrier. This allows to keep lines and links that are associated with the regional energy system but are missing the name of the region in the index. Furthermore, it keeps the detail of interconnectors
• Links and lines that are connecting the region with a foreign country can be filtered. OPEX and CAPEX for those links and lines are counted 50/50 between the countries
• Links and lines that do not have the name of the region in the index would not be included in the .filter(like=region) statement. Therefore, if bus0 and bus1 are associated with the region, the index is enhanced by `" {region}" to include those costs. This mostly affects TYNDP links and lines

get_link_opex/ get_line_opex

• links and lines that are allow trade between the region and foreign countries are not associated with costs for the energy that is imported/exported
• the trade volume is multiplied by the marginal costs at the bus that is providing energy
• these costs are added to the total system costs

@lindnemi can revert including the trading costs from the total system costs. Up to you.
