extra conda package files output directory
I'm hoping to have a way to get final conda package in a seprated directory, instead of $output/$platform/$unknown-file-name.conda.
There are some use cases, for example, in CI, that users may want to collect all the conda packages and process them later in another job. In this case the conda repo is unnecessary, and it's hard to find conda packages in $output directory.
As a example, maturin by default build wheels to $target/wheels/*.whl but it has a option to copy wheels to another directory, then users can test wheels or upload them to pypi easily.
Do you have an example of what this option looks like for maturin?
I think we could potentially add an option to copy the packages to a different location but it's also quite important to have them in the structure they are so that interdependencies are correctly resolved between multiple outputs / multiple builds.

It's called --out, but we already have --output at rattler-build so I don't think that's a good name for rattler-build.
maybe --artifacts-path
