remove deltaCap time split for vm_capCum

[tabeado]

Purpose of this PR

Follow up on the removal of the deltaCap time split implemented by Robert (PR #1238). q_capCumNet and the calculation of p22_marginalCapcumBenefit are adjusted to be consistent with the new implementation of deltaCap.

The effects appear to be generally very small. The main exception are prices for hydrogen (see e.g. p.92 & p. 115 in /p/tmp/tabeado/deltaCapCleanup/remind/output/compScen-fullComp-2023-04-06_08.43.12-H12.pdf

Our H2 price is kind of weird - it was being discussed in mattermost but not resolved (?)
SE H2 price collapses under NDC for SSA and for EUR - probably just because we are using old calibration? I.e. calibration would have "constant" demand, and H2 supply is lower in NDC run, so price collapses... if there is a short compscen (plot until 2050) then one can see it clearer probably..

Chris, I added the short compareScenarios2: P:\deltaCapCleanup\remind\output\compScen-FullCompShort-2023-04-06_11.05.22-H12-short

what is the status of this PR? will you continue working on it?

there are small but visible changes: more VRE capacity under baseline, and more electricity under 1.5C
/p/tmp/tabeado/deltaCapCleanup/remind/output

This looks reasonable to me, as usually deltacap(T+1) is larger than deltacap(T) for VRE in the first half of the century, so when this changes involve cumulative capacity going from .5* deltacap(T+1) + 0.5* deltacap(T) to deltacap(T+1), it will increase wind and solar deployment because they are learned faster based on higher cumulative capacities. This will decrease electricity price under 1.5C to increase electrification
