Camera3D Support

These functions are only for Sketches that use the Processing library Camera3D with py5; without Camera3D, py5 will never call them.

It'd be nice to have this installed as an npm package instead

I had installed pyodide with npm but I had the same error as this issue reports and the solution was to install via cdn.

Maybe updating the node or some other dependency will solve the problem, I'll test this later.

If it doesn't work, would installing pyodide via cdn block the merge?

Ahh I see!

If it doesn't work, would installing pyodide via cdn block the merge?

No, I wouldn't go as far as that. It's just that I try to avoid depending on CDN for external code so that Flok also works offline, as an installable package (e.g. for LAN jams). But if we get stuck, we could go ahead and leave that for another future issue/PR.

I tested with the latest version of node.js currently (23.5.0) and the error persists. Maybe we could remove the cdn from index.html and set it to be loaded only when the session is py5, I believe that this way the other targets would continue to work.
I'm not familiar with react (front-end in general) but I'll see how to load via cdn within the py5 wrapper with react

This is probably not needed because flok already has p5 installed as package dependency?

With the installation of pyodide via the CDN, the p5 installed with npm was not found by pyodide, after the installation with the CDN it worked.

I believe that by solving the pyodide problem this will be resolved.

(I didn't test the p5 to see if there was an error due to yet another installation using the CDN, the idea is to remove the CDN, but I'll test it so I can already map it)

I did a quick test and the p5 in the hydra sessions continues to work without any apparent conflicts
