#' Simplify GeoJSON data
#'
#' Takes a [data-LineString] or [data-Polygon]
#' and returns a simplified version.
#'
#' @export
#' @param feature A [data-Feature]<([data-LineString], [data-Polygon],
#' [data-MultiLineString], [data-MultiPolygon])>, or [data-FeatureCollection],
#' or [data-GeometryCollection]
#' @param tolerance (numeric) Simplification tolerance. Default value is 0.01.
#' @param high_quality (boolean) Whether or not to spend more time to create a
#' higher-quality simplification with a different algorithm. Default: `FALSE`
#' @param mutate (boolean) allows GeoJSON input to be mutated (significant
#' performance increase if `TRUE`). Default: `FALSE`
#' @return A simplified feature.
#' @template lint
#' @family transformations
#' @return A Feature of either [data-Polygon] or [data-LineString].
#' @details Internally uses simplify-js
#' (https://mourner.github.io/simplify-js/) to perform simplification.
