👌 Add das_cycler and svd_cycler to plot collection functions

[s-weigand]

This change allows setting a different cycler for DAS and SVD plots.

I introduced an Unset singleton (similar to pydantics Undefined) in order to allow this change without regressing current behavior.

I also deprecated the cycler argument to plot_sv_data and plot_sv_residual since it doesn't have an effect since there is only a single scatter lines plot where the style is overwritten in the plot method call.

Change summary

• 👌 Add das_cycler and svd_cycler to plot collection functions
• 🗑️ Deprecate cycler argument in plot_sv_data and plot_sv_residual

Checklist

• ✔️ Passing the tests (mandatory for all PR's)

Nice workaround with the Unset type. A bit confusing to reason but it shouldn't really be a problem as it's mostly an internal API thing.
