Add configuration option for basin non-simplification

[amedenblik]

Pete S. would like this for Florida. Not a high priority right now due to competing priorities.

Consider options for allowing certain states/regions to show non-simplified basins by default, even if they have >5000 vertices. There are a few options to consider:

• Resolution-dependent non/simplification
• Adding an option in the appConfig file to set certain states/regions to not show simplified basins
