Remove es6-promise from declaration file

[monolithed]

The reason why I'm asking for is:

node_modules/promise-parallel-throttle/build/throttle.d.ts(1,1): error TS2688: Cannot find type definition file for 'es6-promise'.

Could you try version 2.3.1? I removed the @types/es6-promise in favor of settings the lib compiler option in the tsconfig

That works fine, but only with my PR #16

Without my PR:

declare module 'promise-parallel-throttle' {
	import * as promise from 'promise-parallel-throttle/build/throttle';

	export = promise;
}
