Fix fuel factors and adapt convergence criteria for m0 calculation

Fix fuel factors and adapt convergence criteria for m0 calculation

Description

The fuel factor for kerosene and hydrogen in the mass calculation where switched. In combination with high fuel fractions this led to the iteration not converging. The higher fuel factor should not be a problem for hydrogn aircraft since the mass fraction calculation is also different for hydrogen and will lead to lower fuel fractions.

Testing Instructions

1. Test fix in workflow for LR aircraft
2. Initial sizing should now finish instead of being stuck
