tfc_from_efc

The function takes a data table containing ensemble predictions and reduces it to predicted tercile probabilities.
The data table should either have a column 'tercile_cat' or it will be generated in the process (by <code>add_tercile_cat</code>).
In particular, if you don't know the tercile category of the ensemble predictions, your data table should contain hindcasts as well,
such that the tercile categories are calculated correctly.
The probability for 'below', for example, is the fraction of ensemble members predicting below normal (for this coordinate).

Provides tools for processing and evaluating seasonal weather forecasts,
with an emphasis on tercile forecasts. We follow the World Meteorological Organization's
"Guidance on Verification of Operational Seasonal Climate Forecasts",
S.J.Mason (2018, ISBN: 978-92-63-11220-0, URL: <https://library.wmo.int/idurl/4/56227>).
The development was supported by the European Union’s Horizon 2020 research and innovation
programme under grant agreement no. 869730 (CONFER).
