For example, I have a SDF file as follows

Describe the solution you'd like
Currently, the https://api.naturalproducts.net/latest/chem/standardize endpoint accepts the post request, standardizes the molecule and returns a standard set of key-value pairs in JSON, which is perfect. What would be great is to include all the additional properties in the original SDF file as key-value pairs.

Additional context
This way, we can make most out of the original additional data and don't have to map it separately
