Export generateFormData function

[kveperedo]

Description

This change exports the generateFormData function.

When implementing optimistic ui via useFetcher, we need to get the parsed data from fetcher.formData. We cannot use parseFormData because it returns a promise but it's possible if we use the generateFormData function which is not async.

const fetcher = useFetcher();

// This should have the correct json data for optimistic ui
const pendingItems = fetcher.formData ? generateFormData(fetcher.formData) : null

This should also partially resolve this discussion: https://github.com/Code-Forge-Net/remix-hook-form/discussions/24
