Is your feature request related to a problem? Please describe.
No validation strategy, If I switch via tab through inputs, you set aria-invalid, input wasn't even touched, but felte is already validating it.
aria-invalid is great for me, but I'd like to not set it when input were not dirty.

Describe the solution you'd like
I use yup
add validation option (validator(schema, level, etc, validationType: "onChange" | "isDirty" | "etc"))
