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.

By default, the micro:bit display driver will update the GPIO
|
|
pins of the display (pins 4 through 15) by accessing the entire
|
|
GPIO port. This is done for efficiency, however it may interfere
|
|
with other peripherals connected to the same GPIO port. Select
|

this option if other peripherals are connected to the same GPIO
|

port.
