[Support #YMS-779947]: [udunits] ucar.units.ScaledUnit oddities

Christian,

> System.out.println(unit2.getCanonicalString());  // Prints "3600.0 m.s"

> System.out.println(metersPerSecondUnit.isCompatible(unit1));  //
> Prints "true"
> System.out.println(metersPerSecondUnit.isCompatible(unit2));  //
> Prints "false"
> 
> System.out.println(unit1.equals(unit2));  // Prints "false"

The string "600 m / 10 minutes" is parsed like "((600 m) / 10) * minutes".

Use the string "(600 m) / (10 minutes)", instead.
