It would be useful to allow automatic deploy where the stitch app is in a subdirectory of the root of the git repository.

One case is, where the Stitch app is one level down. The root directory has a build process that bundles multiple JS modules with rollup and writes the combined output to a stitch function in the subdirectory.

Example: https://github.com/gmishkin/jeopardy

The general use case is a monorepo where there may be multiple stitch apps deployed from a single repo, and they are located in the relevant part of the repo at some arbitrary level of nesting.
