Conversion constraint documentation

[SisiLimperatrice]

Problem description

I spotted a small error in the mathematical formulation documentation:
Under the Conversion section of the mathematical formulation, when dexcribing balance_conversion_constraint_rule, the efficiency is applied two times both for the carrier production and consumption. The code seems to be right but you should remove the multiplication by the efficiency for the carrier production.

Calliope version

Stable documentation version

Thanks @SisiLimperatrice. This should be fixed in our new constraint documentation (see here). Hopefully it'll be the stable documentation in the next months.

You could still update version 0.6 documentation by updating this docstring in a Pull Request to the 0.6 branch.
