Integrate GRAPPA & molecule-resolver

[Lemonexe]

When user has available only VLE data, but no vapor pressure model or experimental data, the GRAPPA predictive model can be integrated into VLizard to offer at least estimated Antoine parameters for preliminary research

This shall be supported by molecule-resolver to easily search for SMILES from molecule name or CAS id.

For both tools, find out what is the easiest way: integrate into code base | utilize web API?

💭 Note for future: a predictive model for first virial coeffs would be especially valuable!
