Initial CI workflow

[ChrisKeefe]

conda init zsh is failing just like conda init bash and conda init $SHELL

==> For changes to take effect, close and re-open your current shell. <==

+ conda activate prov

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.

Will attempt to manually source the updated files, and will bail on the "right way" if that fails

Done with trying to do this with conda init.

This guy seems to work for #48, so I'm going with it.

source ${CONDA}/etc/profile.d/conda.sh
conda activate prov
