minor bug in fmi3GetBinary & fmi3SetBinary

In the API fmi3GetBinary (in  fmi3Functions.c ) this piece of code is missing.

```C
if (S->isDirtyValues) { 
    CALL(calculateValues(S)); 
    S->isDirtyValues = false; 
} 
```

Also in 
fmi3SetBinary
you need to add this line:

```C
if (nValueReferences > 0) S->isDirtyValues = true; 
```
