todos to make jupyterlite/xeus the default (ie steps to deprectate jupyterlite/xeus-<lang>-kernels

[DerThorsten]

What is needed to replace jupyterlite/xeus--kernels (in particular jupyterlite/xeus-python-kernel):

• [x] at least some documentation on how to use this (https://github.com/jupyterlite/xeus/issues/8)
  • [x] usage with kernels installed from emscripten-forge
  • [x] usage with kernels installed from local PREFIX
  • [x] usage with additional directories mounted
• [ ] expose empack filtering configuration as a parameter (like xeus-python-kernel) (https://github.com/jupyterlite/xeus/issues/12)
• [ ] make tests pass https://github.com/jupyterlite/xeus/issues/14
• [ ] add / port tests jupyterlite/xeus-python-kernel (https://github.com/jupyterlite/xeus/issues/7)
• [x] release on PyPI / release on conda-forge (does this need to be also on npm?) (https://github.com/jupyterlite/xeus/issues/15)

Probably needed:

• [ ] documentation on readthedocs #17
