The original MIDAS history API does not have provisions for storing TID_STRING data,
it is a very unfortunate limitation that has been with us for a very long time.

If I ever get around to rewrite the MIDAS history API, I will definitely add support for TID_STRING data.

But not today.

K.O.

P.S. Support for arbitrary binary blobs is also possible, but this will make the midas history
a kind of "a daq inside the daq" thing, probably we do not want to go this direction.
