Future Conda Support

We switched to the conda-forge channel, and are using miniforge or pixi to have a fully open-source approach, which does not fall under the Anaconda Inc licensing. Those tools “prefer” conda-forge by default. Pixi, a new tool getting a lot of popularity in the scientific Python community. It actually “prefers” to use conda-forge packages over the PyPI ones due to the more consistent binary compatibility, as the conda-forge folks make sure their toolchain for compiling the fleet of packages is compatible across them. That’s not necessarily true for the PyPI wheels when mixed with other packages coming from conda-forge (some dependencies may use incompatible compiler versions, etc. that may cause failures such as segfaults – very famous one is the mix of pyqt5 and qt5 from conda-forge with pyqt5 from PyPI, installed on top of the conda-forge provided packages.)
