Format tokens as a raw representation for storing token streams.
The format is ``tokentyperepr(tokenstring)\n``. The output can later
be converted to a token stream with the `RawTokenLexer`, described in the
`lexer list `_.
Only two options are accepted:
`compress`
If set to ``'gz'`` or ``'bz2'``, compress the output with the given
compression algorithm after encoding (default: ``''``).
`error_color`
If set to a color name, highlight error tokens using that color. If
set but with no value, defaults to ``'red'``.
