use mamba instead of conda if available

[Joost Kranendonk]

Hi! Thanks for developing your awesome tool! Are you planning to rely on mamba in case it is installed? It is very fast compared to conda and because of that may be well suited for your project.

Reading through your package, it may be as simple as adding the following at the start in function condax.conda.ensure_conda():

def ensure_conda():
    mamba_executable = shutil.which("mamba")
    if mamba_executable:
        return mamba_executable

Yeah this can probably be refactored to use ensureconda (another library that does a lot of that kind of stuff). Do you want to submit a pull request?

[Joost Kranendonk]

Sure! I'll experiment with it and submit a PR. 👍

I've lost interest for this. Closing this for cleanup. :)
