Reads a document to the end of reader and decodes it as a T: the same value or error as
from_json(T, text) for the same bytes, however they arrive (a pipe written in small pieces,
a socket). The pieces are gathered in one buffer that is freed before this returns. A reader
that fails gives a .READ error naming the Io_Error; a document over options.max_size
is a .LIMIT error and the rest of the stream is left unread. The reader is not closed.
