id_info.json Structure

The id_info.json file contains metadata for each subject in the dataset. Extracted from the raw dataset. The structure is as follows:

{
    "id_1": {
        "len": 1000, # Length of the time series data
        "sensor_downtime": {
            1: {
                "time": [yyyy-mm-dd hh:mm:ss, yyyy-mm-dd hh:mm:ss],
                "index": [start_index, end_index]
            },
            2: {
