Load model output into a trials table format

Is your feature request related to a problem? Please describe.

• We need a way to load the model results.
• The model results should be in the same format as the "trials table", and can easily be merged onto the trials table.
• The additional columns will depend on the model but should have the naming scheme of "<model_name>_<column_name>". This naming scheme allows us to merge multiple behavioral models and compare them
• Column names might include Q values or other latent variables, choice prediction, or goodness of fit metrics.
