Implement everywhere_powerplants

[euronion]

Changes proposed in this Pull Request

The combination of conventional_carriers and extendable_carriers currently only allows for expanding conventional capacities in locations, where historically powerplants of that carrier where located.
This PR adds a new configuration option to place conventional powerplants at every network node, irrespective whether powerplants have historically existed there.

Not sure why the environment.fixed.yaml got reformatted automatically by pre-commit

LGTM, nicely documented :)

These errors are what I get for changing the variable names last minute ._.

Btw.: Reformatting of environment.fixed.yaml and missing REUSE compliance of the file related bf5c323 because it was pushed directly. Fixing it here.
