Finished port to SDL3, this has caused several breaking changes from SDL such as lowercase key constants now being uppercase and mouse events returning float instead of int.
Be sure to run Mypy on your projects to catch any issues from this update.

Changed

• Updated libtcod to 2.1.1
• Updated SDL to 3.2.16
  This will cause several breaking changes such as the names of keyboard constants and other SDL enums.
• tcod.sdl.video.Window.grab has been split into .mouse_grab and .keyboard_grab attributes.
• tcod.event.KeySym single letter symbols are now all uppercase.
• Relative mouse mode is set via tcod.sdl.video.Window.relative_mouse_mode instead of tcod.sdl.mouse.set_relative_mode.
• tcod.sdl.render.new_renderer: Removed software and target_textures parameters, vsync takes int, driver takes str instead of int.
• tcod.sdl.render.Renderer: integer_scaling and logical_size are now set with set_logical_presentation method.
• tcod.sdl.render.Renderer.geometry now takes float values for color instead of 8-bit integers.
• tcod.event.Point and other mouse/tile coordinate types now use float instead of int.
  SDL3 has decided that mouse events have subpixel precision.
  If you see any usual float types in your code then this is why.
• tcod.sdl.audio has been affected by major changes to SDL3.
  • tcod.sdl.audio.open has new behavior due to SDL3 and should be avoided.
  • Callbacks which were assigned to AudioDevice's must now be applied to AudioStream's instead.
  • AudioDevice's are now opened using references to existing devices.
  • Sound queueing methods were moved from AudioDevice to a new AudioStream class.
  • BasicMixer may require manually specifying frequency and channels to replicate old behavior.
  • get_devices and get_capture_devices now return dict[str, AudioDevice].
• TextInput events are no longer enabled by default.

Deprecated

• tcod.sdl.audio.open was replaced with a newer API, get a default device with tcod.sdl.audio.get_default_playback().open().
• tcod.sdl.audio.BasicMixer should be replaced with AudioStream's.
• Should no longer use tcod.sdl.audio.AudioDevice in a context, use contextlib.closing for the old behavior.

Removed

• Support dropped for Python 3.8 and 3.9.
• Removed Joystick.get_current_power due to SDL3 changes.
• WindowFlags.FULLSCREEN_DESKTOP is now just WindowFlags.FULLSCREEN
• tcod.sdl.render.Renderer.integer_scaling removed.
• Removed callback, spec, queued_samples, queue_audio, and dequeue_audio attributes from tcod.sdl.audio.AudioDevice.

Fixed

• Joystick.get_ball was broken.
