Preact 10.0, generic types and missing updates

• Wouter now is fully-compatible with Preact 10.0! You can install Preact version via npm install wouter-preact #88, thanks @developit
• Type definitions now support generics, handy if you want to specify a shape of props your component accepts #87, thanks @ArnaudBarre
• useLocation now also catches updates that may happens between the initial render and useEffect call. See #85
• Redirect component now uses useLayoutEffect to trigger the update as soon as possible and prevent apps from flicker.
