* add `useDefaultValue` hook
This allows us to have a guaranteed `default value` that never changes
unless the component re-mounts.
Since the hook returns a stable value, we can safely include it in
dependency arrays of certain hooks.
Before this change, including this is in the dependency arrays it would
cause a trigger or change of the hook when the `defaultValue` changes
but we never want that.
* do not handle `reset` when no `defaultValue` or `defaultChecked` was provided
If a `defaultValue` is provided, then the reset will be handled and the
`onChange` will be called with this value.
If no `defaultValue` was provided, we won't handle the `reset`,
otherwise we would call the `onChange` with `undefined` which is
incorrect.
* update changelog
