-The Sparkfun Library is quite heavy, unfortunately, and it's very limited because of its un-changeable display size. I didn't take the time to create my own program here, I just took the example one and modified it a bit. I don't recommend using this lib, there are other ones that are better and more optimized.

 I'm running this program on a Pro Micro. The compiler indicates 11886 bytes (41%) of program space used, 819 bytes (31%) of dynamic memory. The logoBitmap variable takes 1130 bytes of program space on its own (14110 bytes (49%) without it).
