ThermalNetwork has a component DataFrame 'thermal_networks'

[jnnr]

'thermal_networks' appears as a component of ThermalNetworks, as can be seen by:

thermal_network = dhnx.network.ThermalNetwork()

print(thermal_network.components)

# {'thermal_networks': Empty DataFrame
# Columns: []
# Index: [], 'thermal_sub_networks': Empty DataFrame
# Columns: []
# Index: [], 'producers': Empty DataFrame
# Columns: []

This is potentially confusing and should be corrected.
