Testing basics for Binary unit support

[erikbosch]

With this change I can run

erik@debian6:~/vss-tools/tests/vspec/test_structs$ vspec export binary --types VehicleDataTypes.vspec -u ../test_units.yaml -q ../test_quantities.yaml --vspec test.vspec --output hej.binary

For comparision, similar command works for yaml

erik@debian6:~/vss-tools/tests/vspec/test_structs$ vspec export yaml --types VehicleDataTypes.vspec -u ../test_units.yaml -q ../test_quantities.yaml --vspec test.vspec --output hej.yaml
