Problem

Dead (unused) code in our code base related to serializer/deserializer logic for mol v3000, sdf, smi. it's implemented on the Indigo side.

The declaration of supported formats: /ketcher-core/src/application/formatters/formatterFactory.ts

Solution

• remove file/ketcher-core/src/domain/serializers/mol/v3000.js as not maintained and refactor dependencies.
• remove folder /ketcher-core/src/domain/serializers/sdf as not maintained and refactor dependencies.
• remove folder /ketcher-core/src/domain/serializers/smi as not maintained and refactor dependencies.
