Add SSD1305 support to SSD1306 integration along with few new options (#1902)

Browse source 
* Add serveral options for SSD1306 integration
* Add SSD1305 support
  (SSD1305 is similar to SSD1306, it seems SSD1305 has
  brightness and color register but does not have charge pump)
* Add some description when manipulating registers
* Add flip, offset and invert option to get more compatibility
  with various display modules
* Fix typo `setup_ssd1036' -> `setup_ssd1306'

* Add SSD1306 brightness validation tip

* Add more description, limit offset range

* Changes according to linter

* Fix test

* Raise error instead of using warning

* Fix wrong logic

* Remove logger

Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com>

* Remove logging import
