Migrate Sample Size and Power Calculation

[hendraet]

Issue description

The old PROTzilla repository has an open PR for integrating sample size and power calculation into the tool. This PR should be adapted and integrated also in this repo.

The "Other Output" tab was originally designed to display the minimum power and sample size, but it seems overkill to create a new frontend element for displaying a single number. It would be easier better to display this info in a table and also add it as an additional element on the generated plots. Then, the additional tab can be removed (see also #123).

Acceptance Criteria

• The code is adapted/fixed and migrated to this repository (including tests).
• Additional information regarding power/sample size is displayed in a table and also added to plots.
• The other output tab is removed.
