SDIF-tuples and SDIF-info features request

Hello,

-- SDIF-tuples needs a way to access the data without knowing the
dates. Something like "next" and "end".
-- in this case, SDIF-tuples needs a second outlet with the non
interpolated dates.
-- SDIF-tuples needs a bang when the stream is finished.

-- SDIF-info needs a way to dump the dates from the SDIF file.

have a good day !!!
