How to use the timemory.options function in timemory

Args:
        - data (list):
            - list of "plot_data" objects
            - should contain their own plot_parameters object
        - files (list):
            - list of JSON files
            - "plot_params" argument object will be applied to these files
        - combine (bool):
            - if specified, the plot_data objects from "data" and "files"
              will be combined into one "plot_data" object
            - the plot_params object will be used for this
