ENH: Reduce file size (#433)

Close #430

Several improvements:
1. PDF files of the documentation have been compressed using
`ghostscript` as described
[here](https://www.digitalocean.com/community/tutorials/reduce-pdf-file-size-in-linux)
using the `\ebook` setting (and for some of them, only the interesting
pages remain)
2. Patterns in the TikZ pictures have been replaced with a simple fill
colour to reduce the size of the SVG output.
3. PNG and JPG images of the documentation have been converted into
`webp` files using the commands

    ```bash
find . -name '*.jpg' -exec sh -c 'convert $1 ${1%.jpg}.webp' sh {} ';'
find . -name '*.png' -exec sh -c 'convert $1 ${1%.png}.webp' sh {} ';'
    ```

4. HTML files located in the `doc/_static/` folder have been minified
using the [minhtml](https://github.com/wilsonzlin/minify-html) command
line tool:

    ```bash
minhtml --keep-closing-tags --minify-css --minify-js --minify-doctype
doc/_static/**/*.html
    ```

    The biome formatter has been disabled for this folder.

5. The script to generate the HTML plots of the networks has been
updated to generate new static HTML files (considering #418 and #426).
The code to plot all the networks of the catalogue on the same map is
purely a large copy-paste of the code used to plot the networks
individually. Only a few lines of code are adapted, but I would rather
not refactor the entire plotting module for a single plot.
