Update Germany specific costs (NEP, onwind, pellets)

[lindnemi]

Hopefully for the last time. Firstly, all NEP costs have been updated / double-checked. Most importantly, the offwind cable costs are now more accurate (and lower) and the offwind station costs are more expensive. Interestingly, underground cables in NEP23 are cheaper than in NEP 21 (when correcting for inflation)

The new costs are:

Paramter & unit	NEP 23	NEP 21	NEP 23 Inflation corrected	NEP 21 inflation corrected
AC overhead (€/MW/km)	1325	736	1196	732
AC underground (€/MW/km)	4711	3386	4252	3369
AC offwind (€/MW/km)	618	854	558	850
DC overhead (€/MW/km)	0	1000	0	995
DC underground (€/MW/km)	3300	3250	2978	3234
DC submarine (€/MW/km)	0	0	0	0
DC offwind submarine (€/MW/km)	3000	2000	2708	1990
DC offwind onland (€/MW/km)	3800	3250	3430	3234
DC inverter pair (€/kW)	0	600	0	597
DC offwind station (€/kW)	1000	750	903	746
AC offwind station (€/kW)	800	700	722	697
Inflation	1.108	1.005
