Fix estimation for sequestration potentials

[toniseibold]

Ensuring that the optimistic sequestration potential is equal or greater than the neutral estimation. In raw data e.g. data/CO2JRC_OpenFormats/CO2Stop_DataInterrogationSystem/Hydrocarbon_Traps.csv optimistic assumption is zero in some cases while neutral estimations are > 0.

Removing "conservative estimate Mt" from config since this leads to double counting of the sequestration potential in rule build_clustered_co2_sequestration_potentials.

• before: total sequestration potential of 89,982 Mt
• after: total sequestration potential of 16,227 Mt
