Support validation for Boxed values

[dron8552]

Now there is no validation function that supports Boxed value validation.

Indeed, your are absolutely right. I completely missed this. I'll add support for boxed values to all validation functions where it makes sense (i.e. required, etc.) with the next minor version update. Until then you call always wrap the validation functions and call unbox yourself, i.e.

const validateForm = updateGroup<MyFormValue>({
  myBoxedObject: validate(value => required(unbox(value))),
});

Holy hell, half a year has already passed. I just released support for validation of boxed values in the latest release (wanted to still do this in 2018 ;) ).
