--binary-only or --artifact-include= flags

[rolandwalker]

Per the discussion in #2921, since Casks can support multiple artifacts of different types, it would be desirable to give the user a way to control which artifacts are installed.

Currently we have a --no-binaries option. This could perhaps be generalized to --artifact-include= and --artifact-exclude=.

The use-case discussed in #2921 is: installing only symlinks to executables (binary artifact) when the App itself is already installed via the App Store. For that particular use-case, the binary artifact would also need to be extended to check multiple locations for the symlink source.

Closing for lack of interest/implementation.
