V3: memory-location

[molefrog]

The second essential hook that will be included in the next release. Why: mostly for testing and maybe for environments that don't support location (Electron?).

Specs:

// no `use-` here since it is a high order hook
import { memoryLocation } from "wouter/memory-location"

// simple usage
const { hook } = memoryLocation({ path: "/initial-path" })
const [location, navigate] = hook()

// initial path is "/" by default
const { hook } = memoryLocation()

// must support `base` option for nested routing
const [location, navigate] = hook({ base: "/app" })

// standalone `navigate` method for navigating outside of components
const { navigate, hook } = memoryLocation()
navigate("/users")

// `static` option makes it immutable
const { hook } = memoryLocation({ static: true })
navigate("/users") // nothing happens

// `record` option for saving the navigation history
const { hook, navigate, history } = memoryLocation({ record: true })
navigate("/lol")
history // ["/lol", "/"]

After this hook is ready, we can migrate our tests to use memory location instead of relying on "test-utils"
More ideas?
