ejson available on openSUSE

Hey,

thanks for publishing ejson. Really a very nifty tool! Using it with both chezmoi and ansible.

Just wanted to share that it's also available packaged for installation on openSUSE for all relevant distributions as part of the "utilities" project: https://build.opensuse.org/package/show/utilities/ejson

I didn't want to presume to add it to the README directly, but perhaps this is useful.
