Draws a string located in program memory to the display.
This function will draw a string located in program memory to the display, this differs from gfx_mono_draw_string() by using constant string data from the program memory instead of string data in RAM.
Using program memory for constant strings will reduce the applications need for RAM, and thus lower the overall size footprint.
