Expert Mode: Check Cyton Impedance on both N and P pins

[retiutut]

Is your feature request related to a problem? Please describe.

A user has requested that we be able to check the impedance on both Cyton pins.

Describe the solution you'd like

Add the functionality to the Cyton Signal Widget to check both pins. It's only useful when connecting electrodes to both the top and bottom pins for a channel. New users may not understand why we would check both pins if they are doing EEG.

A few users may also see value in saving this values to a separate file.

Maybe this should be hidden behind "expert mode".

The space already exists in the UI. See attached screenshot.

Describe alternatives you've considered

We excluded this functionality initially since no team or community members saw value in this feature or requested it. Not very useful when doing EEG recordings, which require one electrode on the N pin only per channel.

Additional context

Screenshot for reference.

Looking forward to this feature in the next version. Sometimes I need to check my EOG electrodes as well.
