Move other CDR to Emissions|CO2|Other Capture and Removal

[laurinks]

Purpose of this PR

1. Move DACCS and EW from Emissions|CO2|Other to Emissions|CO2|Other Capture and Removal
2. Also add OAE to Emissions|CO2|Other Capture and Removal (no OAE in last submission, but as preparation for future submissions)

@merfort : Looking at CDR across models, I realized that we map DACCS and EW to Other, not to Other Capture and Removal. Other teams map to Other Capture and Removal. Should this be corrected for future submissions or is there a good reason for this in light of the emissions harmonization process?

Todo:

• Build Library

Checklist:

• I did not use Excel to open csv files or checked that no side-effects occur (changed values, many new quotation marks, …)
• I added any renamed piam_variable to renamed_piam_variables.csv to guarantee backwards compatibility.

It is recommended to have a look at the tutorial before submission.

There are a few reporting issues listed in the ScenarioMIP CDR sheet. Would be good to correct them with this PR.
