Remove clamping functionality from AbsHumidity type

- Remove ClampedAbsHumidity function and Clamped() method
- Remove clamping call in RelHumidityFromAbsC function
- Update Test_AbsHumidity_EdgeCases to remove clamping tests
- Update README to remove references to clamping for AbsHumidity
- Addresses feedback from maintainer that clamping is only needed for bounded values like percentages

 ### Absolute humidity type and conversions
 
-The [`AbsHumidity`](https://pkg.go.dev/github.com/cdzombak/libwx#AbsHumidity) type represents absolute humidity in grams per cubic meter (g/m³). A clamping [method](https://pkg.go.dev/github.com/cdzombak/libwx#AbsHumidity.Clamped) and [function](https://pkg.go.dev/github.com/cdzombak/libwx#ClampedAbsHumidity) for a reasonable atmospheric range (0-50 g/m³) are provided.
+The [`AbsHumidity`](https://pkg.go.dev/github.com/cdzombak/libwx#AbsHumidity) type represents absolute humidity in grams per cubic meter (g/m³).
 
 An [`Unwrap()`](https://pkg.go.dev/github.com/cdzombak/libwx#AbsHumidity.Unwrap) method also exists to get the raw value as a `float64`.
