richdem python version requirement

Awesome project! Just from poking around, it looks like richdem won't build properly on python versions >= 3.10 at the moment. I'm getting a smattering of errors from gcc while trying to build the wheel. You can confirm this from the following docker images:

python:3.10-bookworm
python:3.11-bookworm
python:3.12-bookworm

# install dependencies if not already installed and try to build richdem
apt update; apt install gcc g++; python3 -m pip install richdem

It's not an issue with this project, but I think it's worth noting that 3.9 is the most recent version of python that can be used for it (until the upstream issue is fixed).

Wait nevermind, see this comment:

I investigated and the latest version on pypi is 0.3.4 from 2018 with a vendored older version of pybind11.
There are more recent releases: https://github.com/r-barnes/richdem/releases
If you install from source with a more recent release, it works.

Compiling richdem yourself or installing it through conda seem to work.

richdem installs via pip on my machine with Python 3.10.12. Still, I just added some text in the documentation that tells users that richdem may be easier to install with pip using Python 3.9. Thanks for the heads up.
