Adjust emission to only include the sector scope

[virio-andreyana]

Closes #19

Changes proposed in this Pull Request

Using the source mentioned in #19 we get the targets for 2035 by interpolating 2030 and 2040 S2 (Scenario 2: 85-90% emission reduction compared to 1990). I've only chosen these sectors:

• Power and district heating
• Other Energy sectors*
• Domestic Transport
• Residential and Services**

If only that sector is chosen, then instead of needing to reach 39.2% of 1990 emissions, we need to reach 19.5%.

Checklist

• I tested my contribution locally and it works as intended.
• Code and workflow changes are sufficiently documented.

Looks good! Thanks @virio-andreyana . I want to note that including the 'Residential and Services**' sector also includes fossil fuel combustion in the agriculture/fishery/forestry sector as noted in the Source FIle.
I guess we can live with this though, as the other option would be to exclude emissions from residential heating which we are modeling.

• Would be helpful if you could also add the three co2 csv files that were used for this to the Repo somewhere (doesn't need to be in this or another PR)
