cu8 signal file not vertically centered

[kroylar]

Expected Behavior

When loading the attached b.cu8 file, the Analog signal path should be vertically centered on the plot, like shown in this quick plot of the same data using matplotlib:

I believe it should be centered because the noise is actually centered at 128, which is half the 8-bit unsigned number representing it.

Actual Behavior

The path is instead placed in the lower half of the plot.

Steps to Reproduce

1. Download the attached b.cu8.log file
2. Rename it to b.cu8
3. Open it in urh
