Provide app bundle

tissue uses several guile libraries, and the state of guile packaging is bad everywhere outside Guix. Potential new non-Guix users of tissue are not going to install Guix just to try out tissue. In order to ease adoption for such users, we must provide ???app bundles??? like those generated by guix pack.

Ideally, these app bundles should be provided for every released version of tissue and the latest development version from the git repository. Careful consideration should be given to the version of Guix used to generate each of these app bundles so that these app bundles can be generated reproducibly.

But, more pragmatically, it may be sufficient to only offer an app bundle for the latest released version since that is what new users will be most interested in.
