BUG: `get_timeseries_essentials` Cannot unpack from a list

[khider]

To reproduce:

filename = '../data/Crystal.McCabe-Glynn.2013.lpd'

#Initialize the lipd object
D = LiPD()

#Load the data
D.load(filename)

ensemble_df = D.get_ensemble_tables()

df = D.get_timeseries_essentials(D.get_all_dataset_names(), mode='paleo')

Data here: https://github.com/LinkedEarth/PyleoTutorials/tree/main/data

get_timeseries_essentials seems to take only 1 dataset at a time. This works df = lipd.get_timeseries_essentials(lipd.get_all_dataset_names()[0], mode='paleo')

Do we need it to work for multiple datasets ?

Yes, needs to work for multiple datasets
