Support for outputting the bundle to a file

[RobertAKARobin]

Deno will create an executable file with e.g. deno bundle src.ts > dist.ts. It looks like this package currently supports bundling, but not really outputting the bundle to a file.

Just use something like this:

"bundle": {
  "cmd": "deno bundle src/index.ts my-bundle.js",
  "desc": "Bundles the server for deployment.",
  "tsconfig": "tsconfig.json",
  "watch": false
}
