Kind request to deprecate package in favor of the official version

Hi Vasaka,

Thanks for publishing this package. In the meantime an [official Meteor integration](https://atmospherejs.com/keymaster/keymaster) has become available.

Would you like to support the official package?

If so, you can hide [your package](https://atmospherejs.com/vasaka/keymaster)
from Atmosphere searches, while still keeping it installable by apps and dependent
packages, by running the following command:

    meteor admin set-unmigrated vasaka:keymaster

Thank you,
The [Meteor official integations team](https://github.com/raix/Meteor-community-discussions/issues/14)
