[Microbit-Python] Image class constructors question

[Damien George]

The docs are wrong.  There are 5 constructors:

Image() - return the blank image
Image(chr) - return an image with the character rendered to the image
Image(string) - return an image described by the string (eg 01110:00000 etc)
Image(width, height) - create a blank image of given size
Image(width, height, buffer) - create an image of the given size,
initialsed by the buffer
