NGC-2023 Test mean-power metrics on tied array resampled voltage stream

[EatonEmmerich]

Checklist (if not applicable, edit to add (N/A) and mark as done):

• If dependencies are added/removed: update pyproject.toml and .pre-commit-config.yaml.
• If new source files are added: add copyright notices dated with the current year.
• If qualification tests are changed: attach or link to a sample qualification report.
• (N/A) If design has changed: ensure documentation is up to date.
• (N/A) If ICD-defined sensors have been added: update fake_servers.py in katsdpcontroller to match.
• (N/A) If the interface between the product controller and an engine has changed, update the
  VERSION constant for the engine (update the major number if sensors/requests have been
  removed/changed, minor number if only backwards-compatible changes have been done).
  Also, update doc/control.rst with the new version.

Closes NGC-2023.
