Headers are sent in reversed order

[madamm91]

I'm using the 1.0.3 version of the library.

Let's see the part of ImageUpload example from README.md.

let header:[String:String] = ["Authorization":"Client-ID"]

In this case the header key is "Authorization" and the value is "Client-ID".
When the request is sent, the server gets this header in reversed order, so the key is "Client-ID" and the value is "Authorization".

In short:
value: key instead of key:value

Fix:
Gem/Gem.swift:110
Should be:
request.addValue(headerDetail.value, forHTTPHeaderField: headerDetail.key)

P.s.: Please specify CONTRIBUTING.md file to clarify the process of contribution.
