Breaking Changes: Switch to named exports

• Switch to typscript! (the library now has types)
• Add a hook which exposes state related to a single text input aka useTextInputState
• Switch to named imports. useFormState is no longer accessible as default import.
• The library now exports 2 hooks
  • useTextInputState
  • useFormState
    You can import both of them like:

import { useFormState, useTextInputState } from '@akshay-nm/use-form-state'
