Improve typing of defaultValue and value

[lensbart]

Disclaimer: I’m still finding my way around this package, but it looks really helpful, thanks.

In the following snippet of code:

const [form, { something }] = useForm({
  defaultValue: {
    something: data.something ?? 'any string value',
  },
  onValidate: ({ formData }) => parse(formData, { schema }),
})

the type of something (in the return value of useForm) is correctly inferred as e.g. FieldConfig<'some' | 'thing' | undefined>. I’d expect the type of something in defaultValue to be restricted to either 'some' or 'thing', as per the inferred type of the corresponding input value. However, I can pass any string value here.

Would it make sense to further restrict the type to only allow for, in this case, the string literal union type?

Thanks!

Same question for value in

const inputs = conform.collection(something, { options, type: 'radio' })
inputs.map((input) => input.value)

This is typed as a string, which is OK for passing it to an <input /> element, but a string literal union would be better here (in case you want to call another function with this value, e.g. onChange)
