Final preparation for spectral fits

If the source has sufficient counts it should be rebinned to allow the gaussian statistics used in fitting software to be applied correctly. An example using the GRPPHA program is:

> grppha myagn_src.ds myagn_src_grp.ds
GRPPHA[] group min 20
GRPPHA[] exit
 ...... exiting, changes written to file : myagn_src_grp.ds
 ** grppha 2.9.0 completed successfully
>

This grouping will be offered as an option within future versions of the especget task.
