Feature request for --data-raw

[detrin]

I had this project in a mind for a while. The idea is prune parts of curl request till there is bare minimum left that gives the same result. I would use your package as a core part for it. However there is a catch.

The usual outputs from (e.g. chrome) dev tools are with --data-raw instead of parsed data, even if the raw data are just valid json. It would be great to have support for --data-raw. Even better it would be to have parsing of --data-raw if it is possible, but that is probably out of scope for this package.

I could try to make the changes and open PR if you feel like it would be desirable.
