Support for 'outflow' value in getNodeValue method

[jubilee2]

The getNodeValue method currently supports retrieving the value of 'overflow'. This issue requests the addition of support for the 'outflow' property, which is distinct from 'overflow' and serves different purposes.

Expected Behavior

The method should allow users to retrieve values for both 'overflow' and 'outflow' properties.

Actual Behavior

Currently, the method only retrieves values for 'overflow' and does not recognize 'outflow'.

Offer to Contribute

I am willing to contribute to the resolution of this issue by making a Pull Request. However, if unit tests are required, I may need guidance on how to create them effectively.

maybe like this

        case swmm_NODE_OUTFLOW:
        return node->outflow * UCF(FLOW);

@jubilee2 I am in the process of overhauling the API and advancing unit tests for them in #162 and #163. I will add this to items to include in that work. We are unable to accept pull requests at this time.
