Improvements
- Many performance improvements. Most visible are in
  calculate_lsm (all metrics: more than 5 times faster with 70% less memory
  allocation for augusta_nlcd; larger increases were found for smaller data)
  and window_lsm (a single metric: more than 6 times faster for augusta_nlcd;
  larger increases were found for smaller data)
- Some performance improvements are related to the new "extras" mechanism, in which several objects
  are precalculated in calculate_lsm
- Creates an internal extras_df object that lists which extras are needed by
  each metric
- Replaces the use of tibble::tibble() with tibble::new_tibble(list()) in most functions.
  This change is partially responsible for improvements of the window_lsm speed
- Replaces raster_to_points with get_points in several places.
  The get_points function is based on the column and row numbers multiplied by
  the resolution, not actual coordinates.
- Replaces table with (faster) tabulate in lsm_p_core
New functions
- Adds a few internal helper functions and documents them, including prepare_extras,
  get_area_patches, get_class_patches, get_complexity, get_enn_patch,
  get_points, and get_perimeter_patch
Bugfixes
- Fixes window_lsm behaviour for situations with NAs values and non-square windows
Various
- Fixes several typos and improves documentation in many places
- Uses object references in most rcpp functions
