Replace request library

The request library is overwhelmingly bloated.

Could you please replace it with another AJAX library like axios?

I want to use this library in an Electron app and bundle size matters for parse time.

Start by locating the request dependency and every place it is used in the repository, then compare the replacement's API with those call sites. The work is done when request is no longer needed, the replacement preserves NAT port-mapping behavior, and the bundle-size concern is addressed for Electron use.
