## Parse date from any format, including ISO 8601

### Description

Three useful functions to parse and format dates.

- `parse_iso_8601` recognizes and parses all valid ISO 8601 date and time formats. It can also be used as an ISO 8601 validator.

- `parse_date` can parse a date when you don't know which format it is in. First it tries all ISO 8601 formats. Then it tries git's versatile date parser. Lastly, it tries `as.POSIXct`.

- `format_iso_8601` formats a date (and time) in a specific ISO 8601 format.
