When the response of lambda contain data of type Decimal, datadog  raise except TypeError: 'decimal.Decimal' object is not iterable
## Expected Behavior
When return response from DynamoDB and DynamoDB contains data of type Decimal

## Actual Behavior
Get data of DynamoDB that contains data of type Decimal and raise next exception   **except TypeError: 'decimal.Decimal' object is not iterable**

## Steps to Reproduce the Problem

  1. Get data from Dynamodb inside handler and return response.


In the code core de [datadog_lambda](https://github.com/DataDog/datadog-lambda-python/blob/main/datadog_lambda/tag_object.py) in the line 37 raises of exception because Decimal is instance of object, but this is not iterable


  ```
    if isinstance(obj, object):
        for k in obj:
            v = obj.get(k)
            formatted_key = "{}.{}".format(key, k)
            tag_object(span, formatted_key, v, depth)
        return
  ```
