feat: create os/arch specific npm optional deps for pact-ruby-standalone

[YOU54F]

Motivation

Currently we provide a fat npm package, with the associated pact ruby standalone library for each supported os/arch combo.

It would be neat to leverage the NPM ecosystems optional dependencies and os/arch resolver, in order to reduce the payload delivered for any particular install (which will be for a single os/arch system anyway when executed)

• updates version number of package.json to required level (patch/minor/major)
• downloads standalone for all os/arch combos
• creates os/arch specific npm package and moves relevant os/arch standalone bindings into package. uses version number of current main npm package
• npm link os/arch specific npm package
• npm build and test project
• publish all os/arch specific npm packages to npm
• update main package.json to reflect updated os/arch npm package version numbers
• publishes main npm package
