👌 Make plot_data_overview able to plot single trace data

[s-weigand]

This change allows plot_data_overview to be able to plot single trace data without crashing on a single axis dataset.
The SVD part of the plot will be skipped since it does not make sense.

Pseudo code to try it our:

from glotaran.io import load_result
from pyglotaran_extras import plot_data_overview

result = load_result("my_result/result.yaml")
plot_data_overview(result.data['dataset1'].sel(spectral=0,method="nearest"))

Change summary

• ✨ Implemented not_single_element_dims util function
• 👌 Made plot_data_overview able to plot single trace data

Checklist

• ✔️ Passing the tests (mandatory for all PR's)
• 🧪 Adds new tests for the feature (mandatory for ✨ feature and 🩹 bug fix PR's)

Looks good. It's important to note that this is not suggesting to use plot_data_overview for plotting single traces, but more that when you end up calling this function in a larger context it doesn't crash when the dataset happens to a single trace.
