Update buffer folder and files naming convention

All references to folders and files inside buffer were updated.
- Base folder to write detector: detector_folder
- Name of the modules inside detector_folder: module_name
- Data grouping folders based on pulse_id: data_folder
- Data grouping files, based on pulse_id: data_file
