Several TS/JS basic types are not defined (like ArrayLike or Iterable)

[Booksbaum]

There are several basic TypeScript (or JS) interfaces and types. Some are already handled and translated into suitable F# types, like Error (-> Exception) or Array (-> IList<'T>):

	let abbrevTypes =
	[
	"Array", "type Array<'T> = System.Collections.Generic.IList<'T>"
	"ReadonlyArray", "type ReadonlyArray<'T> = System.Collections.Generic.IReadOnlyList<'T>"
	"ReadonlySet", "type ReadonlySet<'T> = Set<'T>"
	"ReadonlyMap", "type ReadonlyMap<'K, 'V> = Map<'K, 'V>"
	"RegExp", "type RegExp = System.Text.RegularExpressions.Regex"
	"Error", "type Error = System.Exception"
	"Function", "type Function = System.Action"
	"Symbol", "type Symbol = obj"
	"TemplateStringsArray", "type TemplateStringsArray = System.Collections.Generic.IReadOnlyList<string>"
	] |> Map.ofList

But there are several more such types or interfaces that are commonly used, but not handled by ts2fable. I stumbled across these:

• ArrayLike -> System.Collections.Generic.IList<'T> (-> same as Array)
• PromiseLike -> Fable.Core.JS.Promise<'T>
• Iterable -> System.Collections.Generic.IEnumerable<'T> ? are these two compatible?
• Iterator & IterableIterator -> ? I don't think System.Collections.Generic.IEnumerator<'T> is compatible to any of them?
