Consider to extract HttpAcceptLanguage::Parser into separate gem?

[teohm]

@iain Hi, I noticed the repo is not actively maintained, and most pending pull requests (#56 #58 #61) are related to Rails upgrades.

Have you considered to extract HttpAcceptLanguage::Parser into its own gem? Because by doing that, the new parser gem will have no dependency, and anyone who needs the parser can simply install the parser gem and don't have to wait for the Rails-related upgrades.

What do you think?
