typing

[JaskRendix]

PR:

• bumps python to 3.9 and sets tests for 3.10/11/12
• uses black (default -l88);
• removes all the imports from typing (eg from typing import List -> simply list, from typing import Sequence > from collections.abc import Sequence, etc.);
• typehints 382 > 240

and updates:

    tile_size = None             # (int, int): size of each tile in pixels
    map_size = None              # (int, int): size of map in tiles
    visible_tile_layers = None   # list of visible layer integers

into

    # (int, int): size of each tile in pixels
    tile_size: Vector2DInt = (0,0) (or tuple[int, int])
    # (int, int): size of map in tiles
    map_size: Vector2DInt = (0,0) (or tuple[int, int])
    # list of visible layer integers
    visible_tile_layers: list[int] = [] (or Iterable[int] or Iterable[Any]?)

the alternative is to disseminate multiple asserts around the code

        self._tile_view = None        # this rect represents each tile on the buffer

        self._tile_view = Rect(
            0, 0, 0, 0
        )  # this rect represents each tile on the buffer

same as above (asserts)
