Add MD5-Header option to CLDUploadRequestParams

[izaguirrejoe]

Using OPTIONS, you can see that Cloudinary accepts Content-MD5 as a header when uploading a file. Currently, there is no way to add this or any other headers to a CLDUploadRequest. The Content-MD5 header seems like an important header to allow when uploading from iOS. The Cloudinary Rails/Active storage integration requires the MD5 be present, so this would bring the iOS client up to parity with the Ruby gem.

Hi @izaguirrejoe,

Thanks for contacting us.
We have opened an internal task on our end, to add support for extra headers in the upload request.
Currently I don't have an ETA to provide, but I will update this thread with any new insights.
Thanks
