Language is not taken into consideration when caching / checking the cache

[dannydorfel]

In the Client.php, line 605, the cache key is defined by stories/ . $slug and the options are missing. This causes the client to always return the first cached story when requesting other language versions of a story.

I see. Thank you @dannydorfel .
I see in the code we are also using some "options" that could contribute to defining the key for the cache.
In this case, i would open a PR with and hash (as a suffix of the cache key) calculated on the relevant options.

From the implementation perspective, I think this issue is strongly related to this one: #55 (comment)

What do you think?
