Fix large blacklevel step. Lower 25% of shades are now accessible.
...
There is a large step in brightness from level zero to level one.
After experimenting with various ST7789 options, I found that
decreasing VDV to 0x10 (-0.4V) fixes this issue.
The gamma change reduced the average error in brightness, but with the
underlying issue fixed, the gamma change has been reverted.

...
This change will increase the color accuracy of the PineTime and make UI
development with the simulator easier.

When a full screen refresh is done, apply a vertical scroll during the refresh. This makes the transition from one screen the another one smoother, even if the refresh rate is slow.

Better integration of SPI with DMA and IRQ. Using only 'End' IRQ. Perf could be improved by using 'Started' IRQ to prepare the next buffer while the current one is beeing sent.
