fix(dom): support Typescript 3.1

BREAKING CHANGE:
If you use JavaScript, there are no breaking changes. If you use
TypeScript, then you may have to change some imports, only if you are
using RxJS or Most.js. If you are using RxJS: change
`import {makeDOMDriver} from '@cycle/dom'` to
`import {makeDOMDriver} from '@cycle/dom/lib/cjs/rxjs'` and change
`import {DOMSource} from '@cycle/dom/rxjs-typings'` to
`import {DOMSource} from '@cycle/dom/lib/cjs/rxjs'`. If you are
using Most.js: change
`import {makeDOMDriver} from '@cycle/dom'` to
`import {makeDOMDriver} from '@cycle/dom/lib/cjs/most'` and change
`import {DOMSource} from '@cycle/dom/most-typings'` to
`import {DOMSource} from '@cycle/dom/lib/cjs/most'`.
