refactor: replace any with generics in NumProp and BoolOffProp

Make NumProp and BoolOffProp generic (NumProp<T>, BoolOffProp<T>)
instead of using any, with T inferred from callback parameters at
call sites via the num<T>() and off<T>() factory helpers. Remove
unused num import from leaflet-tile-layer-wms. Fix prettier
formatting issues.
