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.
