[Bug] `DEFAULT_WEIGHTS_ENERGY_CARRIERS` needs to be updated
After #619, the energy carrier weighting factors based on TOE are described in the RTD. The factors are defined however in `constants.py` with `DEFAULT_WEIGHTS_ENERGY_CARRIERS` and those need to be updated to the new values, including all possible fuels.
