[core] The core templates do not include the required cstdint for non-float inputs
## What commit version of aidge do you use
```python
aidge_backend_cpu==0.6.1
aidge_core==0.6.2
aidge_export_cpp==0.3.1
```
## Problem description
The benchmarking method `aidge_export_cpp.benchmark.compute_output(...)` fails with integer inputs as the generated files (`forward.hpp`) reference fixed-sized integers, but do not include their definition (`csdtint`). As this is not a dependency that is visible to the end-user, it probably should be added automatically.
Also the compilation step, in the benchmarking method, should probably check the output of `make` (it tries executing the compiled binary even if the compilation failed).
Here is the output of the example code
```bash
Context: Consumer node Add (Add#0) input #0
[WARNING] - No producer node attached to input#0 for node Add (Add)
Context: Consumer node Add (Add#0) input #1
[WARNING] - No producer node attached to input#1 for node Add (Add)
Context: Consumer node Add (Add#0) input #0
[WARNING] - No producer node attached to input#0 for node Add (Add)
Context: Consumer node Add (Add#0) input #1
[WARNING] - No producer node attached to input#1 for node Add (Add)
