Format tokens with ANSI color sequences, for output in a text console.

Color sequences are terminated at newlines, so that paging the output

works correctly.

The `get_style_defs()` method doesn't do anything special since there is

`bg`

Set to ``"light"`` or ``"dark"`` depending on the terminal's background

`colorscheme`
|
