13.5.0

Added

• tcod.sdl.audio, a new module exposing SDL audio devices. This does not include an audio mixer yet.
• tcod.sdl.mouse, for SDL mouse and cursor handing.
• Context.sdl_atlas, which provides the relevant SDLTilesetAtlas when one is being used by the context.
• Several missing features were added to tcod.sdl.render.
• Window.mouse_rect added to SDL windows to set the mouse confinement area.

Changed

• Texture.access and Texture.blend_mode properties now return enum instances.
  You can still set blend_mode with int but Mypy will complain.
