Create cupid-dev/cupid analysis environments if not already installed

[TeaganKing]

Particularly in the case of running CUPiD from the CESM workflow, we'd like to create cupid-dev/cupid analysis environments if those environments are not already installed.

We could do this by including a bash script that checks if cupid-dev exists, and if it doesn't exist, create the environment. This could look like the following:

FOUND=TRUE; conda activate cupid-dev 2>/dev/null || FOUND=FALSE
mamba env create -f environments/dev-environment.yml
conda activate cupid-dev
mamba env create -f environments/cupid-analysis.yml

Alternatively, we could advise users to install the environments ahead of time, but it'd be nice to have this automated.
