Extracts a named component from an
enw_preprocess_data() or epinowcast() object. List columns
are unwrapped automatically so you get the underlying
data.table or value directly.
Value
The extracted component. For list columns this is the
first element (typically a data.table); for scalar columns
the value is returned as-is.
