Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything or linked relevant results below
• I made sure the docs are up to date
• I included tests (or that’s not needed)

Description of changes

Closes #19.

Adds an opt-in verbose option to directiveFromMarkdown, mirroring verbose in hast-util-from-parse5.
When on, directives with attributes get data.position.attributes: one DirectiveAttributePosition per attribute, in source order, with:

• name: the attribute name (id for #a, class for .a)
• start / end: the whole attribute (#a, .a, a, a=b, a="b")
• value: the raw value without quotes; empty between the quotes for a=""; not present for a

It is a list rather than a record keyed by name because duplicates are allowed and class values are joined:
every occurrence is included, and for a given name the last one is the one whose value is in attributes (all of them, for class).

attributes itself is unchanged, and without verbose the tree is exactly what it was before.

Notes on the implementation:

• positions come from the existing name / value / id / class value tokens, plus a new exit handler for directive*AttributeValueLiteral to cover the quotes (and to give empty quoted values a place)
• the whole-attribute token (directive*Attribute) is not used for start / end, because it includes trailing whitespace for value-less attributes ({a b} gives "a ")
• the # / . marker and quotes are one character on the same line, so those points are shifted by one instead of tracking the marker tokens

Types (FromMarkdownOptions, DirectiveAttributePosition, DirectiveDataPosition, data.position on the three *DirectiveData interfaces) and the readme are updated.
npm test passes, with 100% coverage.
