A wrapper around FastAPI's Depends function that infers its return type from its input

## Example

```python

from fastapi_inferring_depends import Depends

from fastapi import FastAPI

app = FastAPI()

async def answer_to_everything_dependency():

    return 42

@app.get("/answer")

async def get_answer_to_everything(

    answer_to_everything=Depends(answer_to_everything_dependency),

):

    # type of answer_to_everything is 'int' (inferred from dependency)

    return {"answer": answer_to_everything}

```

For more examples, look at the test/example [file](https://github.com/jvllmr/fastapi-inferring-depends/blob/dev/test_example.py) for all supported inferences.
