GLMakie interactive optimization

[maltepuetz]

This is just a cool idea for the future:

Make a GLMakie interface with the following elements:

• residual landscape (2d landscape of the quality function around the optimal parameters, or for user defined p_space)
• plot of the scaled data (maybe also add the option to plot the connecting splines)

Now there could be sliders to dynamically change the parameters and modify the scaled data. There should be a marker in the landscape plot to mark where the current parameters lie. There could also be the option to click on the landscape plot to select parameters.

This may be a very nice interactive way to manually do a scaling! Note: Add this as an extension to not include GLMakie in the direct dependencies :)

Other ideas:

• a plotting extension for CairoMakie, Plots, ... to plot scaled and unscaled data in just a function call -> this should also have the possibility to plot the splines together with the data
• a function to visualize the error analysis, i.e. export data/plot the cost function for the variation of one parameter

mostly implemented, still needs some finetuning / bugfixes
