EXTI

[Usioumeo]

I would like to control myself the method that gets executed when an exti interrupt fires.
Unfortunately, if i try to use bind_interrupts macro it could never link, because in ch32-hal::exti there is another implementation with the same signature.
What is the intended way to do this? Maybe is possible to hide the exti initializzation behind a feature flag in order to have the "ExtiInputFuture" and other things implemented only when you need it? Also it could be enable by default, because the majority of the users would use it.

Let me know what you think

Other than that, why typelevel enum/structs does not contain interrupts like EXTI5, EXTI6, EXTI8.... Why is that? is it intended behaviour?
