Update reqwest to 0.13

[asonix]

Update reqwest to 0.13, exposing new features form and query, and removing previously deprecated fetch_mode_no_cors

[asonix]

publish is failing due to version changes. I bumped the version number because it's tied so closely to reqwest's version

Could this be merged and released please?

Thank you!
