Implements the basic methods required for the turbo-ios adapter. The idea is that the Turbo Native adapters could be usable by client-side libraries other than Turbo, such as htmx. For example, a hypothetical API:

import 'htmx.org'
import Turbo from './turbo-shim.js'
import Driver from './turbo-native-htmx-driver.js'

Turbo.registerDriver(Driver)
