evacpath 0.1.0.9006

Added crop_roads_to_inner_extent() with separate x/y inset controls for escape-point QA/QC.
Added make_road_aware_escape_zone() to combine buffered road corridors with the tsunami escape zone before escape points are generated.
Added roads_for_escape, escape_roads_inset_x_m, escape_roads_inset_y_m, road_aware_escape_zone, escape_zone_road_buffer_m, and escape_zone_crop_buffer_m arguments to run_evacpath().
Added a package-level help page so ?evacpath works after documentation/install.
Reworked the README and diagnostic example so package documentation is place-agnostic.
Added README figures from the packaged example workflow.
Removed old compatibility alias documentation and wrappers from the public API.
