Known differences from the Python microdotphat package

• The Python package clears the display at program exit by default (configurable via set_clear_on_exit); this package does not. If you want this behavior, add this code to your func main:

  defer func() {
  	microdotphat.Clear()
  	microdotphat.Show()
  }()
  

• The Python package has three functions for scrolling the buffer (not including scroll_to). This package collapses those functions into one Scroll function.
• The Python package has functions set_mirror and set_rotate180. This package collapses those functions into one SetMirror function (rotation is achieved by flipping both axes).
