Keep existing conventional generation in sector network

[martacki]

Closes # (if applicable).

Changes proposed in this Pull Request

The sector coupled network currently removes existing conventional generators. This PR adds them back (in the traditional sectoral setup with EU Generators + Links)

Except for typos (my specialty), there seems to be only the same bug as in master, which is why Windows OS is failing (nut sure about why).

Remaining discussion points could be:

• I designed the same setup for nuclear as for fossil generation (Generator uranium connected with a nuclear link). I think that makes more sense, currently it simply remained a "nuclear generator", but this was a bit confusing
• Currently, if existing capacities are kept and the carrier is expandable, only the existing locations can be expanded. The same carrier can not be expanded at a different site, if that site has no existing capacity. Could be potentially fixed, but wasn't needed in our case

Otherwise, seems to work.
Nuclear / coal generation in power only model:

Nuclear/coal generation at sectoral model:

Sectoral model dispatch (in links_t.p1) (Co2L0.5 for whole EU, 121H, 59 clusters)
nuclear

coal

default config settings don't change the current default output (except that nuclear is not kept anymore in the generators)
