Format tokens with IRC color sequences
The `get_style_defs()` method doesn't do anything special since there is
no support for common styles.
Options accepted:
`bg`
Set to ``"light"`` or ``"dark"`` depending on the terminal's background
(default: ``"light"``).
`colorscheme`
A dictionary mapping token types to (lightbg, darkbg) color names or
``None`` (default: ``None`` = use builtin colorscheme).
`linenos`
Set to ``True`` to have line numbers in the output as well
(default: ``False`` = no line numbers).
