Add geothermal-sourced central heat pumps

[amos-schledorn]

Closes # (if applicable).

Changes proposed in this Pull Request

• This feature adds geothermal-sourced central heating based on utilisation potentials by Manz et al. and technology data from the DEA techn. catalogue.
• COP for fixed-source temperature geothermal heat is computed
• Geothermal heat is added as a carrier
• Generation of geothermal heat is bounded by the utilisation potential in Manz et al. (direct usage of hydrothermal heat sources, located close to high-heat-density areas, at 4000 FLH/year, expressed in TWH/year) and scaled by FLH to achieve technical potential in MW)
• Heat pumps convert 1 MWe (electricity) + (1 - COP) MWth (geothermal heat) to COP MWth usable central heat.

Open issues

• DEA technology data refers to 1200m deep geothermal district heating (in contrast to 2000-3000m assumed in Manz et al.)
• Workflow could break down if supply temperature < 65C (hydrothermal temperature)
• Results for low spatial resolution look odd: Geothermal heat is overused as relatively large areas are modelled as heat lakes. This could be remedied limiting the geothermal potential pre-clustering to the NUTS3 heat demand (and then summing the limited geothermal wattage).
• Make workflow unspecific to geothermal (to allow incorporating other output from Manz et al.)
• Workflow accesses config as dict rather than through config_provider, which can break the scenario management (raised by @lindnemi)

Checklist

• I tested my contribution locally and it works as intended.
• Code and workflow changes are sufficiently documented.
• Changed dependencies are added to envs/environment.yaml.
• Changes in configuration options are added in config/config.default.yaml.
• Changes in configuration options are documented in doc/configtables/*.csv.
• Sources of newly added data are documented in doc/data_sources.rst.
• A release note doc/release_notes.rst is added.
