automatically check project summations (AR6, NAVIGATE), bugfixes ar6climate, fixOnRef, policyCosts

[orichters]

Purpose of this PR

• automatically run script that converts remind2 data into AR6 and NAVIGATE data and runs a variable summation check and a regional summation check. Prints results to log. The scripts fails in case of problems, but that fail basically does nothing, except output.R telling the user it failed. The regional summation check has to skip several Emissions|* variables because they have bunkers included on the World level, but not in the regions as this was the default for AR6.
• for fixOnRef, add option cfg$fixOnRefAuto to the config that allows to autocorrect wrong fixing. Not sure whether we want to activate that as usual. I would rather prefer to fix it the EDGE-T issues at the core, but as long as magpie does not know reference fixing, this switch is useful for coupled runs.
• for fixOnRef, use TRUE_or_fixed to avoid asking if the user wants to update if everything is fine
• for fixOnRef, set scenario name correctly for MAGICC6 data. Be more clear what was changed and why.
• add higher memory requirements for nashAnalysis
• if an output/single script does not exist, skip this script, not the whole outputdir
• update _withoutPlus file after writing MAGICC7.5.3 data
• fix bug in policyCosts plotting after I named the data dimension correctly as variable in this remind2 PR but did not adjust this script.

Type of change

• New feature

Checklist:

• My code follows the coding etiquette
• I performed a self-review of my own code
• I explained my changes within the PR, particularly in hard-to-understand areas
• Some automated model tests pass: testOneRegi fails because of this error. Everything before is fine, also codeCheck succeeds, and test_06-output.R also works (after I put some fulldata.gdx into the testOneRegi folder).
• The changelog CHANGELOG.md has been updated correctly
