Option to run Sage cells in the browser using WebAssembly instead of the Sage Cell Server

[mkoeppe]

A part of the functionality of Sage is available for serverless in-browser execution using WebAssembly. https://passagemath.org/passagemath-jupyterlite-demo/lab/index.html

This can reduce latency, eliminate the availability issues with the Sage Cell Server, and enable interactive computational widgets.

(https://pretextbook.org/support.html suggests to discuss ideas on the Google Groups prior to submitting issues, but my request to join pretext-dev was denied.)

@mkoeppe - thanks for posting here. Sorry about the -dev permissions, someone else beat me to it. Would you mind trying again? Maybe say just a bit more about what you want to discuss, and say that I will approve it, and maybe it won't happen agsain. I'll repy to a -dev post one we get there. Thanks. And apologies again for the inadvertent denial.

Thanks @rbeezer, I've resent it.

And should be approved now. Please post a rough game plan on -dev and I'll chime in there.

Thanks, will do!
