Checksum failing

Hello there,

I have checksum failing for this plugin, any idea what might have gone wrong:

```
$ packer init .
Failed getting the "github.com/hashicorp/googlecompute" plugin:
1 error occurred:
* could not get sha256 checksum file for github.com/hashicorp/googlecompute version 1.0.6. Is the file present on the release and correctly named ?
