Version and package management

`conda` and `conda`-like

conda is a package manager that also manages virtual environments.
mamba is a faster drop-in replacement for conda.

They both have their full-fledged version and "mini" version, e.g. anaconda and miniconda / mambaforge and miniforge.

Migrate condainstallation to a different directory

At installation, it's possible to select the directory where the environment will be stored.

After installation:

Simply move the $HOME/miniconda3 (default installation) to the new directory.
Open /path/to/new/dir/miniconda3/condabin/conda and change the !/$HOME/miniconda3/python to !/path/to/new/dir/miniconda3/python.
Run /path/to/new/dir/miniconda3/condabin/conda init to update the shell initialization script.

Usually this will be enough. If not, you might need to update the PATH variable in the shell initialization script.

Use `libmamba` solver for `conda`

# need conda > 22.11
conda update -n base -c defaults conda
conda install -n base conda-libmamba-solver
conda config --set solver libmamba
