Grammar: Support `export * as namespace from`

not support export * as recbar from './recbar.coffee'

It looks like export * as namespace from was added in ES2020: https://github.com/tc39/proposal-export-ns-from, mdn/content#11293.

In the meantime you can do what Babel does:

# export * as namespace from 'pkg'

import * as _namespace from 'pkg'
export { _namespace as namespace }
