Implementation for zip manifest support

Fixes #307 Resolves #309 Resolves #310

This PR implements the functionality for generating and updating zip manifests.

Changes:

Updated the manifest version to v1.4
New command supports extracting a zip file and displaying the available installers to the user if more than one exists. Will skip the installer selection prompt if only one installer exists.
Update command also supports extracting a zip file. Will check that the relativeFilePaths from the existing manifest point to a valid file in the new installer URL. The updated hash comes from the zip and not from the individual nested installer files.
Error will be displayed to the user if the zip is not valid, if the zip does not contain any installers, or if the relativeFilePath does not point to an actual file (Update command).
Updated schema url to an official aka.ms vanity url.

Tests:

Updating a valid and full v1.4 manifest
Updating a zip with exe
Updating a zip with msi
Updating a zip with portable
Updating a zip with msix
Updating a zip with an invalid relative file path (does not point to a actual file in the zip)
E2E test for zip
Verified new command manually with different zip packages.
