[jtpio]

Just tried with #19 locally and also getting a build failure.

This seems related to the solving of the environment:

Some of the packages might now be compatible with emscripten. Maybe we can try using the emscripten-forge channel, until there is something like https://github.com/jupyterlite/xeus/issues/76 supported in jupyterlite-xeus?

Did some expérimentations on https://github.com/stevejpurves/seg_tutorial/pull/1

The UI should ideally stream the build logs, like on mybinder.org.
