Drop Python < 3.10, update runtime dependencies (#854)

This updates dependencies for renewed development here, and in the process, drops support for Python < 3.10. We *mainly* supported older Python versions for Google Colab, and Colab is not on Python 3.11. Unfortunately, we can’t go newer than Python 3.10 either, since we need cchardet support (for now).

+1. Get Python 3.10 or later. If you don't have the right version, we recommend using
    [conda](https://conda.io/miniconda.html) or [pyenv](https://github.com/pyenv/pyenv) to install it. (You don't need admin privileges to install or use them, and they won't interfere with any other installations of Python already on your system.)
 
 2. Install libxml2 and libxslt. (This package uses lxml, which requires your system to have the libxml2 and libxslt libraries.)
