Description

This MR fixes #2200 by moving manual tests inside the manual folder.

This MR also brings back the handy media.py utility and it's been tested with both MicroPython and Pyodide and it works like a charm. I've done that because otherwise the little great camera.py example would've been lost.

I don't know why that lovely file from @fpliger got removed so I'll ping @mchilvers too to maybe know more but I think that file was pretty cool as extra helper.

Changes

• fixed all tests that were outdated
• moved all tests inside the manual folders as those are mostly for quick debugging purpose
• moved the real WebSocket test as part of integration ahead of the rest (to be seen if CI is happy about it)
• updated the good old media.py which now works with modern PyScript and in both mpy and py scripts

Checklist

• All tests pass locally
• I have created / updated documentation for this (if applicable)
