PR#3 updated region retrieval rates to the wrong values #4

Hi, thanks for maintaining this calculator!

I noticed that the results I was getting didn't match the official AWS calculator (http://calculator.s3.amazonaws.com/), and it seems to come down to the retrieval rates.

It seems like https://github.com/liangzan/aws-glacier-calculator/commit/e7547411dea1c2099d3dcff4f1fdd93a8a8c0632 updated them to the wrong values. The examples I see in the Amazon Glacier FAQ all use $0.01/GB. Try as I might, I couldn't seem to find the per-region prices for Glacier retrieval.

If I take this calculator's results and adjust them for the $0.01/GB retrieval rate (in us-east-1), my results line up with the official AWS calculator and with the rudimentary calculation shown by the Glacier "Data Retrieval Policy" screen in the AWS Management Console.

@karpach Are you sure that the retrieval rates in your PR are current?

I got my prices from the official amazon glacier page:

@karpach As an example, in your commit (https://github.com/liangzan/aws-glacier-calculator/commit/e7547411dea1c2099d3dcff4f1fdd93a8a8c0632), you changed the retrieval pricing in regionRetrievalRate() for us-west-2 from $0.011 to 0.055. Based on your screenshot, that value should have remained unchanged.

You are right. Looks like number of the requests is not taken into account by this calculator. I'll submit a fix.
