/*
Duration: 1240 ms
Initial white pulse:
- Required for white-white so that white stays white (pulse can be as low as 2 ticks)
- On black-black to ensure long term stbility (pulse should be 4 or higher for
long term stability)
- Pulse should be short, to avoid flicker
- Long enough for the black-black transition
White pixel (black-white transition)
- Starts at the beginning. Looks like a black pulse is not required.
- White low level must stop before the black pixel are finished
Black pixel (black-black and white-black)
- Black (high level) is extended. If the black level is applied longer, the contrast
gets better.
- There must be no white pixel write otherwise contrast will be bad: Writing
black is put at the end and starts in the middle

update/refresh duration:
(refresh_lines + dummy_lines*2)*TGate*TS_Sum/f_OSC
f_OSC=1MHz (according to the datasheets)
refreh_lines = 296 (for the waveshare display, 0x045 cmd)
dummy_lines = 22 (for the upcoming u8g2 code, 0x03a cmd)
TGate = 62 (POR default, 0x03b cmd)
TS_Sum: Sum of all TS entries of the second part of the LUT
f_OSC: 1MHz according to the datasheet.
so we have
total_refresh_time = 21080*TS_Sum/1000000 = 21ms * TS_Sum
--> this is more or less close to the measure values.
