Gets a glib.bytes.Bytes containing data from body starting at offset.
The size of the returned chunk is unspecified. You can iterate
through the entire body by first calling
soup.message_body.MessageBody.getChunk with an offset of 0, and then on each
successive call, increment the offset by the length of the
previously-returned chunk.
If offset is greater than or equal to the total length of body,
then the return value depends on whether or not
soup.message_body.MessageBody.complete has been called or not; if it has,
then soup.message_body.MessageBody.getChunk will return a 0-length chunk
(indicating the end of body). If it has not, then
soup.message_body.MessageBody.getChunk will return null (indicating that
body may still potentially have more data, but that data is not
currently available).
