The buttons on the microbit cause quite easily "ghost" key presses.
Add a simple filter that ignores button presses from the same button
that happen less than 100ms from each other.

The stuff that the GPIO button callback does (in particular the printk
calls) requires more stack space from the ISR stack. Increase it to 1k
from the default 640.

Add beeps whenever the ball hits the walls or the paddle. Requires a
piezo buzzer connected to pin 0.

Add initial draft of a pong game using the display on the micro:bit
and its two buttons. This draft only supports a solo game where the
ball bounces from the "roof" and lets the player play against himself.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

Both the string and image rendering may want to take advantage of
scrolling and sequential display capabilities. Consolidate the APIs so
that there's a single one for images (mb_display_image) and a single
one for strings (mb_display_print). Both take a duration parameter for
the per-frame duration as well as a mode parameter which specifies
sequential vs scrolling behavior as well as an optional looping flag.

Docs need a label at the top so we can use :ref:`labelname`
to create a link to that doc from other docs.

Add a new mb_display_print() API which takes printf-style parameters
and outputs scrolling text instead of one character at a time. The
existing mb_display_str() API is renamed to mb_display_string() for
consistency, and now also takes printf-style parameters.

Adds a simple driver to access the 5x5 LED display found on BBC
micro:bit boards. The display is so limited that no effort is done to
try to integrate with the existing console (which would likely make
the display unusable). Instead, dedicated mb_display_* APIs are added
that are specific to this display.
