Added checks for GDS scalefactor (DBU) both when reading GDS in

Browse Source 
"gds readonly true" mode and when writing a GDS file in full-dump
mode.  Reading or writing a file with an incompatible DBU is now
prohibited.  This is not a great solution, as it forces the
original file to be rewritten with a different DBU.  Preferably
there should be code to scale the units during a dump, but that
needs to be coded.
