Fix for integrated_bioprocess.py

[zasddsgg]

Thanks for your fix. A few other files seem to be needed to be changed as well (https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/tree/master/biorefineries/cellulosic/systems/fermentation), for example in integrated_bioprocess.py, DAP load of seed train seems to be 0.33 g /L as well (while it should be 0.67 g /L).

@zasddsgg, got it! All fixed across all files. Feel free to reopen the issue if I missed anything.

Thanks,
