Remove exporting visualisation so that CarboKitten loads up faster

[EmiliaJarochowska]

Currently importing CarboKitten loads up plotting dependencies, which takes long, especially the first time. Skip exporting plotting as default so it can be imported when user intentionally wants to plot.

• [x] migrate dependencies to separate work environment
• [x] update documentation
• [x] update scripts to generate figures

Created a separate workenv where all the big dependencies for interactive use go. Now CarboKitten itself only depends on HDF5 and Transducers. Still need to update documentation and Makefile though.

One snatch: if you work in a different branch, you need to tell workenv that you want to use that branch of CarboKitten.

Anyway: just running CarboKitten itself (and generating the HDF5 files) should be much snappier now. Another way to make things a bit better is to create an executable image including some of the heftier plotting dependencies (see: https://docs.julialang.org/en/v1/devdocs/sysimg/).

Not sure if this is a good solution, please see https://github.com/MindTheGap-ERC/CarboKitten.jl/issues/28#issuecomment-2014836821 Anyways it would be helpful to have the instructions completed so we know how you intend it to be run.

I would vote against adding this complexity. This project has a substantial abstraction level already, so hard enough, especially for first time users.

I have added CairoMakie under [weakdeps] and made the CarboKitten.Visualization submodule such that it only produces figures when CairoMakie is imported, otherwise it'll print a friendly message.
