Configurable pixi install location and cache dir

[imagejan]

Would it be possible to install pixi in a location different from the default $HOME/.pixi, e.g. by providing an environment variable PIXI_HOME?

In our environment, we access various linux machines where $HOME points to a network location with limited space. I'd rather like to specify different locations (e.g. on a network location with larger quota) for 1) the .pixi location and for 2) the Cache dir (something else than ~/.cache/rattler/cache, similar to how I can specify the PIP_CACHE_DIR environment variable).

These will both be in the next release 🎉
