- New method of cleaning panel (should work on most ED060SC7 panels)
- New method of displaying greyscale image (using simple, our experimental waveform)
- Added partial update (works only in 1 Bit mode!)
- Faster data sending (still only bit-banging)
- Clean sequence is now inside display() function (user does NOT have to call it before every time before display() like on prev. version of library).
