This function returns an updated version of
chem.physical_and_invitro.data
that includes quantitative
structure-property relationship (QSPR) predictions from Simulations Plus'
ADMET predictor as
used in Sipes et al. 2017, included in sipes2017
.

Only matters if load.image=FALSE. If overwrite=TRUE then existing data in chem.physical_and_invitro.data will be replaced by any predictions in Sipes et al. (2017) that is for the same chemical and property. If overwrite=FALSE (DEFAULT) then new data for the same chemical and property are ignored. Funbound.plasma values of 0 (below limit of detection) are overwritten either way. |

Because Clint and Fup are the only measurements required for many HTTK models,
changing the number of chemicals for which a value is available will change
the number of chemicals which are listed with the get_cheminfo
command. Use the command reset_httk
to return to the initial
(measured only) chem.physical_and_invitro.data
(for all
parameters).

# We should be back to our original number:
