anchor_txt: attributes in markdown

anchor_txt adds the ability to embed attributes in markdown files so that external tools can more easily link them to eachother and code, as well as perform other operations.

Use anchor_txt.Section.from_md_path to load a markdown file.

Markdown Syntax

The syntax for anchor_txt attributes is simple.

• Headers of the form # header {#anchor} will have the anchor tag extracted and available in Header.anchor
• A header creates a Section, which can have sub sections.
• Sections have attributes, which are embedded yaml either inline or in fenced code blocks, shown below.

An inline attribute looks like one of these:

`@{foo}`
`@{bar: 2}`

Fenced code block attributes look like below. They must include the identifier yaml (or json) and end with a @

```yaml @
foo: null
bar: 2
```

Attributes blocks within a Section are combined through the same process as dict.update, except overlapping keys throw an error.
