bcmaps 1.0.1

• When R version is >= 4.0, bcmaps will use tools::R_user_dir("bcmaps", "cache") to determine the cache directory, while when R version is < 4.0, it
  will use rappdirs::user_cache_dir("bcmaps"). This is to align with CRAN's
  storage policy using the tools approach while maintaining backwards
  compatibility with older R versions. Unfortunately this will require users who
  updated to version 1.0 to re-download layers because we are caching layers in a
  different location on your file system from that version. Users wishing to clear
  the old cache location could run bcmaps::delete_cache() before updating to bcmaps 1.0.1.
  (#83)
• cded_raster and cded_stars directly accepts a bounding box generated by sf::st_bbox as an aoi. (#87)
• Fixed a bug where bundled datasets (e.g., mapsheets_50K(), mapsheets_250K()) would not work if sf was linked to older GDAL/PROJ libraries due to different formats of coordinate reference systems. (#85)
• Added new census boundary layers: census_dissemination_area(), census_metropolitan_area(), census_tract() (#82).
• Add missing layers to available_layers
