Artifacts using Webmockr (2)

A simple HTTP client, with tools for making HTTP requests, and mocking HTTP requests. The package is built on R6, and takes inspiration from Ruby's 'faraday' gem (<https://rubygems.org/gems/faraday>). The package name is a play on curl, the widely used command line tool for HTTP, and this package is built on top of the R package 'curl', an interface to 'libcurl' (<https://curl.haxx.se/libcurl>).

Utilising the 'Have I been pwned?' API (see <https://haveibeenpwned.com/API/v2> for more information), check whether email addresses and/or user names have been present in a publicly disclosed data breach.
