import { getManifest } from "https://deno.land/x/deno_slack_hooks@1.3.0/get_manifest.ts";
Returns a merged manifest object from expected files used to represent an application manifest:
manifest.json, manifest.ts and manifest.js. If both a json and ts or js are present,
then first the json file will be used as a base object, then the .ts or the .js file export
will be merged over the json file. If a .ts file exists, the .js will be ignored. Otherwise,
the .js file will be merged over the .json.
