UriData.fromUri factory constructor

UriData.fromUri(Uri uri)

Creates a DataUri from a Uri which must have data as Uri.scheme.

The uri must have scheme data and no authority or fragment, and the path (concatenated with the query, if there is one) must be valid as data URI content with the same rules as parse.
