✨ Add a-matrix inspection function

[s-weigand]

This change adds a new sub package for inspection functions (pyglotaran_extras.inspect) and the show_a_matrixes function to render all a-matrixes in a ResultLike optimization result.
The rendered matrixes are wrapped in a html details tag per dataset, which is collapsed by default.
Inside the details tag, the matrixes are placed under a heading with the corresponding megacomplex name.

Here is an example of what output looks like, for more examples have a look at the markdown preview of the added unit test data:
