Re-export reqwest?

[h4l7]

The current version of this library is out-of-step with reqwest. The most recent version of reqwest is 0.12.4, but this library uses 0.11.4. To prevent issues like the following, could this crate re-export reqwest so we can always use the correct version, even if we use a newer version of reqwest elsewhere in our code base?
