RPE and CB data analysis notebooks

These are the notebooks that perform (for both Reward Prediction Error (RPE) and Cognitive Bias (CB) experiments):

1. A reconciliation of the the log files whose data will be loaded into the databases.
2. The parsing of the log files into the respective databases (one for RPE and one for CB^ data)
3. Sample queries for using the data in both DuckDB databases.
4. Allowing for manual corrections to the CB data (in progress).

^This is a work in progress for the CB data.
