Selecting just "p" (power) does not work

Joulescope model

JS220

What OS are you seeing the problem on?

Windows 11

What happened?

When selecting just p (power) in both the device control widget for a JS220 and in the waveform, nothing is displayed.

What was expected?

At full rate, the device cannot simulteneously support streaming i, v, and p. Instead, it computes p from i and v. However, it should support any combination of i, v, and p by streaming the correct signals from the host. In the case that all three are selected, it should compute p by multiplying i and v.

As of Sep 2023, downsampling is still performed on the host, so we expect this to behave the same at downsampled rates. However, once we move downsampling to the JS220, we can stream all three signals at downsampled rates.

How to reproduce?
