MicroPython logo example with termbuf

I made a MicroPython logo example for termbuf, with two pixels missing for "the eye" from the MicroPython logo. The code lives in my termbuf repository, and running it in the terminal first meant I only had to flash the device once instead of flashing and reflashing.

The two missing pixels are "the eye", as in the MicroPython logo. IYKYK.

The code is at github.com/nmattia/termbuf/blob/main/examples/mpy_logo.py, and the HACKING file covers running the example.

Using termbuf saved me a ton of time flashing and reflashing. Once it worked in the terminal, I just had to flash once.
