feat(docs): Add a means of testing public docs.
The public docs are written in a semi-literate programming style. Semi-literate in the sense they aren't written in a Knuth Literate Programming style, which is a complex and comprehensive system for creating multiple program files from multiple document files. The semi-literate programming uses a simpler approach, one markdown file to create one code file, which I think is preferable in this case.
Semi-literate programs differ from doc-tests because code blocks in doc-tests are isolated: one code block has no bearing on another. Instead a semi-literate program blocks are expected to accrue from top to bottom. In a way, it's like writing a program but flipping it from default code and exceptional comments to default comment and exceptional code.
This commit adds a literate-tests crate internal to docs that can be directed to extract Rust or Python code from markdown files and then test, exercise, or check formatting of those of those files. In this way, the aim is to bring the public docs under our regular CI test regime, so that they will be flagged when changes break them.
