Second cava_data call in vulnerability notebook maxs memory on HUB and crashes kernel

[elehmer]

Second cava_data call in vulnerability notebook (cell 11) uses up all the memory in the HUB instance and crashes the kernel. This is the code call:

data = cava_data(
    ## Set-up
    example_locs, # no subsetting for a single location from input list
    time_start_year=2020, 
    time_end_year=2050,
    downscaling_method="Dynamical",  # WRF data
    approach="Time",  
    wrf_bias_adjust=False, # return all WRF models
    
    ## Likely seaonal event specific arguments
    variable="Air Temperature at 2m", 
    metric_calc="max", # daily high temperature
    percentile=75, # likeliness percentile
    season="summer", # season
    units="degC", # change units
    
    ## Export
    export_method="calculate",  # export only calculated metric data
    file_format="NetCDF",
    batch_mode=True, # batch mode - optimized for multiple locations
)
