Enhance DCM-Net functionality in app.py by integrating support for multiple DCM layers, updating the rendering of 3D models, and improving the user interface with sliders and buttons. Extend dcm_app.py to create and load models for DCM-3 and DCM-4, and adjust weight loading to accommodate additional models. Update requirements.txt to include new dependencies for molecule visualization.

Refactor weight loading in dcm_app.py to use JSON instead of pickle, adding a new function for restoring arrays from loaded data.

Refactor weight loading in dcm_app.py to use pickle for parameter files, replacing pandas with a dedicated function for loading dictionaries.

Enhance DCM evaluation by adding normalization for batch inputs and updating the evaluation function to accept a variable number of DCMs; include print statement for results in app.py.

Refactor app.py to integrate DCM functionality and streamline molecule visualization; update requirements.txt to include plotnine and correct dcmnet repository URL.
