The benchmark runner spawns new processes for each configuration. The specific configuration is transfered by process.argv. This means that the values have to be parsed. As of right now only numbers and strings are parsed correctly. However other values such as objects where used. This fixes the benchmarks that used non-string/number values and prevents future issues by asserting the type.
