Compact version of get_duplicate_forecasts()

[nikosbosse]

Maybe something like the following would be nice.

Normal output

ex <- data.table::copy(example_quantile)
ex <- rbind(ex, ex[1000:1110])
duplicates <- get_duplicate_forecasts(ex)
duplicates

Compact version:

fu <- get_forecast_unit(duplicates)
duplicates[, .(n_duplicates = .N), by = c(fu)]

Could e.g. be an argument compact = TRUE or something like that.

agree. This would be a good issue for a new contributor
