Automatically generate C/C++ header file when building shared library

I am reading about Codon's [C/C++ integration](https://docs.exaloop.io/codon/interoperability/cpp) and it seems that there is a need to manually translate
```python
@export
def foo(n: int):
```
into
```c
int64_t foo(int64_t);
```
It would be nice, if
```bash
codon build -o libfoo.so foo.codon
```
automatically generated C/C++ header file, that could be included from C/C++ code:
```c
#include "foo.h"
```
Go language has this functionality. Running
```bash
go build -o libfoo.so -buildmode=c-shared foo.go
```
will generate `foo.h` as well as `libfoo.so`.
