Apply a mapshaper command string to a geojson object

Apply a mapshaper command string to a geojson object

apply_mapshaper_commands(data, command, force_FC, sys = FALSE)

`data`	geojson object or path to geojson file. If a file path, `sys` must be true
`command`	valid mapshaper command string
`force_FC`	should the output be forced to be a FeatureCollection (or Spatial*DataFrame) even if there are no attributes? Default `TRUE`. FeatureCollections are more compatible with rgdal::readOGR and geojsonio::geojson_sp. If FALSE and there are no attributes associated with the geometries, a GeometryCollection (or Spatial object with no dataframe) will be output.
`sys`	Should the system mapshaper be used instead of the bundled mapshaper? Gives better performance on large files. Requires the mapshaper node package to be installed and on the PATH.
