bindings : add Ruby (#500)

* adding ruby bindings

* avoid adding these they are copied in via extconf.rb

* ignore these files here

* add definitions for boolean params

* initial transcribe for ruby

* use en model and transcribe jfk with assertion

* possibly this works for building ruby binding

* ci : try to add ruby workflow
