Add ability to use custom curve number tables other than the default TR-55

Many jurisdictions publish their own set of curve numbers for different land uses which they will expect to see during plan review. The local curve number sets often differ from TR-55. Please allow us to build custom curve number sets based on land use and soil type. Additionally, these custom curve number sets should be able to be saved in a library for use across multiple projects or at least able to export/import.

    If you use CN hydrology then this is an import and needed option.
