A datatype containing media that is part of a multi-part `Content` message.

A `Part` consists of data which has an associated datatype. A `Part` can only
contain one of the accepted types in `Part.data`.

A `Part` must have a fixed IANA MIME type identifying the type and subtype
of the media if `inline_data` or `file_data` field is filled with raw bytes.
