srep_new and srep_old use the same srep compressor during compression, but include different decompressors in "Setup.dll" depending on _new or _old.

Previously CIU had two selection modes to include the srep which was "SREP N" or "SREP O", then changed to "SREP NEW" or "SREP OLD" (Full names of N or O).
As DiskSpan_GUI already creates the file with the decompressors, the choice of the decompressor is made in this way.
PS: srep_old has only 32-bit decompressors, but srep_new is the beta version of CLS srep (It is not a final version).
I don't know why we still use the old version, but I think that in some cases the new version may not be a good choice.
