clip_ftw: Clip Fietstelweek data to a study area of interest

In loreabad6/ftw: Explore Fietstelweek data for delimited study areas

Description

Clips the Fietstelweek data on a system directory to a study area within the Netherlands, either a municipality or a province for 2015 and/or 2016 and saves it as three files: edges.gpkg, nodes.gpkg, routes.csv. It can be used after applying the downloader_ftw function, or providing the user's self-downloaded data.
