FUNCTION_DESCRIPTION

1	summarize_data(in_data, var, comp_quant, FUN, band_n, selband)

`in_data`	`data.table` containing raster values (for a full file or a "chunk")
`var`	`character` name of the variable (i.e., column) to be used as grouping variable for summarization
`comp_quant`	`logical` if TRUE, percentiles of the distribution are computed alongside standard statistics
`FUN`	`function` if not NULL and is a valid function, FUN is used for summarization and only its results are reported. Useful for example for analyses over large high-res raster since it reduces memory footprint (see `sprawl::aggregate_rast`)
