This release adds a `get_cell()` function to GridLayout which allows you to lookup cell contents by their x,y cell location within the grid. Previously it was only possible to get them by their index which was tied to the order they were added to the GridLayout.

See this for an example usage of the new function: https://github.com/adafruit/Adafruit_CircuitPython_DisplayIO_Layout/blob/main/examples/displayio_layout_grid_layout_get_cell_test.py
