rebinned ASCA GIS rmf files

[Lorraine Breedon <breedon@ros10.gsfc.nasa.gov>]

We announce release of gis2v4_0_256.rmf and gis3v4_0_256.rmf.
These files are made just rebinning gis2v4_0.rmf and gis3v4_0.rmf
into 256 channels from original 1024 channels using the ftool
rbnrmf (v4.4.0).  These are made for spectral analysis of GIS data 
having 256 channels.  Although Guest Observers are easily able to
create these files by themselves, we put these files in the
CALDB to save GOs efforts.

These datasets should be flagged as good in the CIF.
