Like *Label, *ChemicalStructure is a new special, expects a SMILES and will use CDK Depict (Toolforge) to visualize the chemical structure in 2D

Fixes #1427

Description

Added some more Scholia logic to "recognize" *ChemicalStructure columns and then expects a SMILES (canonical or isomeric) and will use the Toolforge CDK Depict instance to display the 2D structure. The column gets renamed to * structure (like with *Description).

Caveats

There is a change (like with *Label) that we accidentally use if for something other than SMILES (rare, I expect).

Check any of the following which apply:

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update
  • I have made corresponding changes to the documentation
• This change requires new dependencies (please list)

Testing

The patch uses this new functionality on the taxon page:

• Try pinus: http://127.0.0.1:8100/taxon/Q12024#metabolome

Awesome, thanks!
