RTL Support

Hello,

I needed to add RTL support for this plugin in a project where I use it. I would like to send a PR that enables RTL support for it. This works like this: You either set a new config option rtl: true or set a class on any ancestor. The option does that as well, sets a class. The result is the flag is displayed on the right and phone number is right-aligned.

Let me know.

I actually found a simpler, and arguably better solution.

Since a) the dropdown list is always in English (+ localized name), and b) phone numbers should be written Left to Right in all languages, then it actually makes sense to simply wrap the input control with <div dir='ltr'>. When this is done, all is good with the world again.

I think if you just mention this in the README somewhere, most users who require RTL will be satisfied.

My slim code (on Rails), for reference:

.field.col.span-6
  = f.label :phone
  div dir='ltr'
    = f.telephone_field :phone, dir: 'ltr', class: 'align-left'

And on that note, I want to say this plugin works flawlessly. I was worried it will mess up my CSS style, or look weird in most situations, but it looks very natural. Well done.

Thanks! Theoretically it would be good if the div that is created to wrap the input would have dir=‘ltr’
