Kind request to deprecate package in favor of the official version

Hey @yasinuslu / @mangasocial,

Thanks for publishing this package. In the meantime an [official Meteor integration](https://atmospherejs.com/isotope/isotope) has become available.

If you'd like to support the official package, it would be great if you can hide [this one](https://atmospherejs.com/mrt/isotope-repackaged) by running `meteor admin set-unmigrated mrt:isotope`. 

If that doesn't work, maybe you were originally the maintainer on the old package system. You can attach your Meteor Developer account at http://atmosphere.meteor.com/accounts, then ping @tmeasday to give you ownership of the old package.

Thank you,
The [Meteor official integations team](https://github.com/raix/Meteor-community-discussions/issues/14)
