Plugin no longer supported as of packer v1.11.0

[CoryManson]

This plugin no longer appears to work as of Packer v1.11.0

https://github.com/hashicorp/packer/releases/tag/v1.11.0

Breaking Change: Support for loading plugin binaries following
the naming convention of packer-plugin-name has been dropped. Packer will now only load
plugins stored under the Packer plugin directory using the expected namespaced
directory and CHECKSUM files. This change drops support for loading plugin
binaries in Packer's executable directory or a template's current working
directory. hashicorp/packer#12828

Use packer-plugin-cross to use as simply as:

packer init your-board-file.pkr.hcl
packer build your-board-file.pkr.hcl

works wonders with 1.11.1 😃
