Aggregation for sub-hourly data

### What problem does your feature request solve?

We need to be able to aggregate for sub-hourly model output data such as R2O;'s suites or the urban-scale configs.

### Describe the solution you'd like

### Describe alternatives you've considered

Start by searching the repository for existing aggregation logic and the code paths that handle model output data. Clarify the required sub-hourly inputs, aggregation periods, and expected results for R2O suites or urban-scale configurations before implementation. Done should include a defined behavior and tests for the supported sub-hourly data.
