Force include directories in build

[mipyykko]

Perceived Problem

Our project has a directory of scripts that are run as cronjobs etc. None of them are imported from outside this directory, and none of them import nexus, so they are not emitted to the build created by nexus build. To include these in the build, we have to build the project with tsc with noEmit: false and copy the scripts to the existing, nexus-generated build.

Ideas / Proposed Solution(s)

Provide a way to define directories to be included in the build.
