Ability to opt of of "No routes matched location" warnings

[AndrewLeedham]

In Remix I have implemented a custom express integration where 404's fall-through to other express middleware. This works great, however we get warnings that react-router does not match any routes, which is expected and an un-needed warning in our case.

It would be great if we could opt out of this warning firing:

react-router/packages/react-router/lib/hooks.tsx

Line 430 in 4b494b9

warning(

Also, as a side not in regular development one log is easy enough to ignore. But in e2e testing it floods the output.
