TTY setup

val setup : 
  ?style_renderer:Fmt.style_renderer ->
  ?utf_8:bool ->
  out_channel ->
  Format.formatter

setup ?style_renderer ?utf_8 outc is a formatter for outc with Fmt.set_style_renderer and Fmt.set_utf_8 correctly setup. If style_renderer or utf_8 are specified they override the automatic setup.

If outc is stdout, Fmt.stdout is returned. If outc is stderr, Fmt.stderr is returned.
