Subject: [PATCH] feat: Only generate manifest if update is specified (#8)

* Only generate manifest if update is specified

BREAKING CHANGE: packwatch will now exit with a non-zero code if run
without an existing manifest file and without the --update-manifest
flag. Now run packwatch --update-manifest to generate a manifest for the
first time.

* Fail but still generate manifest
