implement renewable share targets for NPi runs based on NewClimate protocol

[fschreyer]

Purpose of this PR

This addresses https://github.com/remindmodel/development_issues/issues/438.

It adds renewable share target implementation to the NPi2025 realization of the techpol module based on new data of the NewClimate policy protocol. Targets can be switched on/off via new switch cm_RenShareTargets. By default the renewable share targets are on. It removes the hard-coded constraint of the EUR renewable share target from before.

Generally, there are only small differences in the EUR region for NPI2025 of some higher renewable shares with the targets on (see below).

Note: As a new input file is added, this PR increments the input data revision for REMIND to 7.72. Hence, this PR also introduces changes unrelated to renewable share targets to REMIND via a new set of input data. This is fine with @LaviniaBaumstark.

Thank you, Felix, for that great work!

I would just like us to double-check why we don't think the NPi tech targets (incl. ren share targets) should be the default.

[RahelMA]

That's an elegant way to solve over the four types, thank you!

[RahelMA]

Thanks for the quick changes; it looks good to me now! Maybe in another PR, we should set NPi2025 as default for techpol!

[fschreyer]

Ok nice! It is already default here. ;-)
