Add support for 'soft framebuf' adafruit_framebuf
We will be removing built-in framebuf and moving to displayio in 4.x. In the meantime (and on boards without space for displayio like the trinket m0) you can have a slow-but-working soft framebuf. this has now been added. Please delete any old framebuf.mpy files and use https://github.com/adafruit/Adafruit_CircuitPython_framebuf instead. Thanks!
To use in CircuitPython, simply install the Adafruit CircuitPython bundle.
To use in CPython, pip install adafruit-circuitpython-ssd1306.
