Hardcode support for platform pyodide_wasm32

Also cahnge some Generators to Tuple, as it is not the first time that
while debugging I exaust the generator when printing logs; and this make
micropip installing the package to fail.

I don't like it; this feels like a hack, but it works, and I woudl be
happy to get more guidance.

Also one weird thing, is if I installl pywavelets nightly, it installs
numpy stable; while the index does have a numpy nightly;

And with the same config, if I ask it to install numpy; it does install
numpy nightly.

So there is something wonkey in recursive dependency handling of
indexes.
