[teqc] Problem when combining hourly data.

I think this in fixed in the development code; it's been tested on
sample intervals of 0.05 sec (decimating to 0.5 sec) and 1 sec (decimating
to 30) sec, for both raw and RINEX input files.  The bug was buried in
the decimation code changes allowing for more obvious decimation syntax when
the intervals are less the 1 sec, but only occurred (i.e. returned to the
original sample interval) for the 2nd and later files of the input (for
any original sample interval).
