Patch requests for stlite playgrounds which require GET calls

[arnaudmiribel]

Description

Stlite playgrounds are disabled for certain extras because they require GET requests to collect a dataset and requests doesn't work by default with pyodide. Fortunately though, there's a library which offers a patch to that! See code here https://github.com/koenvo/pyodide-http#supported-packages - we may just add a parameter patch_requests which would add the following requirements to stlite as well as the necessary header code!
