Add HTTP Request extension

[federico-terzi]

I've noticed a lot of packages rely on curl to execute HTTP requests and obtain the expansion text.
It might be a good idea to introduce a "request" extension so that use-case is solved without the use of an external command

I think this Feature could be interesting to let wttr package work again?

For those still having issues with expansions that relied on the curl command when using Windows. There is a fairly easy workaround to restore this functionality.

The issue appears to, at least in my case be, that after Microsoft disabled Internet Explorer it crippled curl (alias for Invoke-WebRequest) in older versions of Powershell in the process. A solution for this I have been using, is to install the latest version of Powershell "Powershell 7" then calling upon this new version by adding pwsh -command before curl e.g. cmd: "pwsh -command curl '<URL>'".
