[Feature Request]: Transform values on submit

[crutchcorn]

This feature request comes from houseform/houseform#60, the older form library I maintained

Description

Ideally, I'd like to have a number, displayed as a string (say, a locale with 1,000,000) and then transform this number back during the field submission.

 <Field
  name="number"
  initialValue={'0'}
  // This is the magic
  transformOnSubmit={v => parseFloat(v)}
  onChangeValidate={z.coerce.number().min(1, 'Must be at least 1')}
/>

Hey @crutchcorn, mind assigning me this for me to work on? 🙏

[crutchcorn]

Done! Thanks for taking this on @CheRayLiu.

Something worth considering is how we will/should handle TypeScript typings for transformations.

Unassigned myself for now as I don't see myself working on it any time soon

[crutchcorn]

No worries @CheRayLiu! Thanks for being willing in the first place :)
