Out directories should be named based on circuitId instead of filenames

```
{
              "cID": "mul",
              "fileName": "testtemp/circuit2.circom",
              "proofType": "groth16",
              "compilationMode": "wasm",
              "powerOfTauFp": "./tests/data/out/powersOfTau28_hez_final_14.ptau"
           },
```

should have out/mul instead of out/circuit2
