A version of Terminal.renderIO that checks ANSI support?

This is a common pattern in `dhall`:

```haskell
do
supportsANSI <- System.Console.ANSI.hSupportsANSI System.IO.stdout

Pretty.Terminal.renderIO
System.IO.stdout
(if supportsANSI
then docStream
else (Pretty.unAnnotateS docStream))
```

Could `prettyprinter-ansi-terminal` export a version of `renderIO` so I could write something like this instead?

```haskell
Pretty.Terminal.renderIOCheck System.IO.stdout docStream
