A date picker web component, based on duet date picker, except authored with Lit and using shadow DOM.

This is a work in progress.

Todo:

• Convert to Lit and use Shadow DOM
• Add support for formdata event
• Port test suite to web-test-runner and mocha
• Extract calendar component
• RTL support
• add valueAsDate property
• add valueAsNumber property
• add validity property
• simplify user parsing/formatting. named capture groups for parse? format string?
• configurable disallowed chars
• month component
• imperative API?
• Perhaps support slotting your own input?
• date range component?
• date picker readonly
• css parts
• Decide on project/tag name
• track bundle size
• configurable short day names? looks like there's a lot of variation and substring(2) might be bad e.g: https://www.ema.europa.eu/en/documents/other/abbreviation-names-days-calendarised-blisters_en.pdf
• docs!
