Encode/decode/parse data: URIs API

Encode text or a base64 payload into an RFC 2397 data: URI (chosen MIME type, charset, base64 vs percent-encoding), decode an existing data: URI back to its payload, or parse one into its structural parts (mediaType, parameters, base64 flag, decoded length). Handles both base64 and URL-encoded data URIs via an 'op' of encode|decode|parse. Answers 'turn this text into a data URI','decode this data: URL','what MIME type is this data URI'.
