Fix for "get_app_store_version_number" for apps with limited availability

[stef-t]

I've been using get_app_store_version_number with the bundle_id parameter and came across the following error, although the provided bundle id matched the bundle id of my published app on the AppStore:

Cannot find app with #{bundle_id} bundle ID in the App Store

Trying with different bundle ids, I realized that an app's availability influences the result of the itunes lookup API:

• App available in multiple countries: itunes lookup API finds the app.
• App available in one country: itunes lookup API cannot find the app. (The app in question is currently only available to my local country.)

When supplying the url parameter country with a country code to the itunes lookup API call, it will find both apps!

The pull requests, adds a new parameter country to get_app_store_version_number. If country is passed as parameter, it is added as url parameter value when calling the itunes lookup API.

Thank you! Did you have a chance to look at the JSON parser error I mentioned above?

@stef-t Sorry, I haven't yet -- I'll have a dig through when I get a moment !

@stef-t - I may of led you awry slightly by saying the existing request is a good example - might be some magic in the headers and how they interact with the network mocking* (maybe content length actually) - but I simply re-cURL-ed the request for ya and it worked ! Go figure 🤷‍♂️

Must be some header magic then. Good thing it was so easy to fix for you!
