Many qudt:symbol values with more than one divider symbol (slash)

... for example this beauty:

unit:FT-HR-PER-GAL_UK
  qudt:symbol "lb/(gal (UK))/(lb/(ft·h))" ;

The regex

qudt:symbol "\(?(.+)\)?/\(?.+\)?/.+\)?

finds 177 of such symbols in the units file.

This is an artifact of the unit symbol generation in qudtlib. It's best not to fix these manually (much work), I'll make a PR once qudtlib is fixed.

Actually, not an artifact of a qudtlib bug... so we can use qudtlib to correct all the symbols. PR coming up.
